In this section we will focus on adjacent angles, but we will also briefly review their "siblings," corresponding angles, alternate angles, opposite angles and collateral angles.

Generally speaking, angles are an integral part of many geometry problems. These angles are usually formed by lines, some parallel and some intersecting. Our ability to differentiate the different types of angles can help us solve geometry problems at all stages of learning. In this section we will focus primarily on opposite angles.

In many geometry problems we are asked to work with different types of angles. These angles are formed when two or more lines intersect, or when one or more line intersects two parallel lines. Knowing the properties of these angles will help us to solve most geometry problems. In this article we will focus on the so-called collateral angles.

Often, when we are faced with geometry problems, we come across different types of angles that are formed by parallel or crossed lines, which help us to solve exercises in an elegant and efficient way.

Are complicated multiplication problems getting you down? They don't have to anymore! Today we're going to learn how to simplify those migraine-inducing, multi-factor multiplication expressions by using the **associative property of multiplication**.

Have you ever come across a messy addition problem? Wish you could just rearrange the operations to make it easier? Well, you can! The associative property of addition lets you do just that.

To make things easier when solving algebraic problems, we have a few *properties* that we can use to simplify expressions. Think of them as tools you can use to reshape an expression. The main properties we are focusing on at this level are: the associative, the commutative and the distributive properties. In this article, we get to know the associative property and its uses.

As we move forward, let's take a moment to briefly review our other properties: the distributive and the commutative properties.

Does the commutative property addition seem fairly intuitive - great! Now, let's take things a little further by exploring the commutative property of multiplication. This property is another useful tool that allows us to simplify and solve multiplication exercises efficiently and easily.

Do you feel like you've mastered multiplication? The times tables are easy for you? Well, then it's time to take multiplication further - with **exponents**! Exponents tell us how many times to multiply a number by itself. They also allow us to write a large number in a simple way. When will I use this? Continue reading to explore exponential numers and their different applications.

What shape are the dice in your board-game? That's right, they're **cubes**! Did you know that most ice-cubes aren't actually cubes? A cube is a type of cuboid in which all three dimensions (length, width and height) are identical, which means that each face is a perfect square. Open the closest freezer and take a look at the ice tray - are those ice-cubes made up of perfect squares? If not, maybe we should be calling them ice-cuboids instead!

A cuboid is a three-dimensional shape that we encounter every day of our lives. They come in all different sizes, and serve many different purposes. Food containers, matchboxes, closets, shipping containers and more! Probably the most common type of cuboid we will come across is called a rectangular cuboid.

It is not complicated, although it does require a basic understanding of the concepts behind the theory. In this article, we will try to explain them in a simple and clear way.

The first step to solving a scary, complex multiplication equation is to simplify it. Often, what seems complicated is actually fairly simple. This is where the distributive property comes to helps us! The distributive property helps us to rewrite our expressions by breaking down large numbers into smaller, more manageable chunks.

Does using the distributive property seem easy by now? Great! It's not so hard, it just takes some practice. Let's go a bit deeper - now we'll explore the *extended* distributive property. Here we'll see expressions with **two sets** of parentheses. Don't worry! Using the same principles that we've already learned, we'll find that the extended distributive property isn't any different than the basic distributive property.

The distributive property is a tool that helps us to simplify complex expressions by breaking down large numbers into smaller, simpler terms.

The quadratic function, or the parabola, is a function that we will work with a lot throughout the years of studying mathematics in high school, so it is important to understand what it means and what to expect when solving its questions.

The ratio describes the "relationship" between two or more things. The ratio links the given terms and describes how many times greater or smaller a certain magnitude is than another.

Questions about scale deal with the relationship between the actual dimensions of an object and those of the drawing that represents it.

Inverse proportionality indicates a situation in which, when one term is multiplied by a certain number of times, the second term is decreased by the same number of times and vice versa.

Direct proportion indicates a situation in which, when one term is multiplied by a certain amount, the second term undergoes exactly the same thing.

Sometimes we will be given only a whole ratio between two terms and a third piece of data that is part of another ratio. Usually, it will be stated that there is a proportion between the ratios and that we must find the missing data in the ratio.

Many students believe that proportionality is a super complicated topic, but believe me, it's not like that at all, it's entirely based on ratio or relationship and circumstances you have already studied.

In a division according to a certain given ratio, we will have a defined quantity that we must divide according to that ratio.

Equivalent ratios are, in fact, ratios that seem different, are not expressed in the same way but, by simplifying or amplifying them, you arrive at exactly the same relationship.

There are 4 criteria to determine that two triangles are congruent. In this article, we will learn about the third criterion of congruence: Side, Side, Side.

There are four criteria to determine when two triangles are congruent. In this article, we will study the second criterion of congruence: Angle, Side, Angle. We will look at some examples to understand how to use this criterion.

Whether you are preparing for a test or are about to take university entrance exams, it is essential to know how to calculate the area of a triangleâ€”regardless of its type (right angled, isosceles, etc.). So, how do you calculate a triangular area? This guide will clear up all of your doubts concerning one of the most frequently asked questions in geometry exams.

Logarithmic laws are an excellent example of yet another pair of scary words encountered during math studies, but if you delve a little deeper into the topic and understand what's behind these words, the fear can completely dissipate.

Did you notice the quadrilateral that is formed at the intersection of 2 train tracks? What is it called? What are its characteristics? Let's take a look at the train tracks, why are there 2 parallel tracks? For the train to not derail, there must be 2 tracks that always maintain the same distance from each other. This is the definition of parallel lines that never meet because the distance between them is always the same. At the moment when 2 train tracks intersect, a quadrilateral is formed between them, which has 2 pairs of opposite sides parallel, which is the parallelogram. In this article, we will talk about what a parallelogram is and learn how to prove it.

An integral part of the curriculum also includes geometric shapes, which feature, among other things, the rhombus. It's important to note that even if you are a high school student, you will still be asked to solve problems that include these same shapes, rhombuses included. So, how do you calculate the area of a rhombus?

Often, when we sit on the beach facing the sea, we observe a good number of kites. Have you examined their shape? It's a deltoid shape. The deltoid has a somewhat complicated shape. It is a quadrilateral but not a square, and it has a shape similar to a rhombus and a parallelogram, but their definitions are different. In this article, we will learn what a deltoid is and how to identify it.

Percentages are one of the most studied topics in mathematics. And one of the most common exercises that every math student must know how to solve is how to calculate percentages.

More than once, we've heard the principal telling the teacher, "Have you noticed that there is no overlap between the students and the study material? Well, your goal is to create that overlap." So, what is an overlap in everyday language? Overlap is a coincidence between two or more elements. Also, when we talk about triangles, we can find different types of coincidences. There are triangles that are equal only in their angles and are called similar triangles, and there are triangles that are equal in both their angles and sides, being identical to each other. We will call these latter triangles congruent triangles, and we will learn about them in this article.

What are those mysterious square roots that often confuse students and complicate their lives? The truth is that to understand them, we need to grasp the concept of the inverse operation. What do we mean by this? When we solve an exercise like "How much is 5 squared?" it's clear that 5 multiplied by 5 gives us a result of 25. This is the concept of powers or, to be more precise, squaring a number. To apply it, we multiply the figure or number by itself. But what happens when we encounter an exercise where X squared equals 25? In this case, we must perform an inverse operation, and this is when square roots come into play.

In this article, we'll start by recalling the definition of an "exponent," and then we'll focus in an organized manner on the different rules of exponents:
