The measure of angle C is 90°, therefore it is a right angle.
If one of the angles of the triangle is right, it is a right triangle.
Right triangle
What kind of triangle is given in the drawing?
As all the angles of a triangle are less than 90° and the sum of the angles of a triangle equals 180°:
The triangle is isosceles.
Isosceles triangle
What kid of triangle is the following
Given that in an obtuse triangle it is enough for one of the angles to be greater than 90°, and in the given triangle we have an angle C greater than 90°,
Furthermore, the sum of the angles of the given triangle is 180 degrees so it is indeed a triangle:
The triangle is obtuse.
Obtuse Triangle
What kind of triangle is given in the drawing?
Given that sides AB and AC are both equal to 9, which means that the legs of the triangle are equal and the base BC is equal to 5,
Therefore, the triangle is isosceles.
Isosceles triangle
Which kind of triangle is given in the drawing?
As we know that sides AB, BC, and CA are all equal to 6,
All are equal to each other and, therefore, the triangle is equilateral.
Equilateral triangle
What kind of triangle is given here?
Calculate the size of angle X given that the triangle is equilateral.
Given the values of the sides of a triangle, is it a triangle with different sides?
Choose the appropriate triangle according to the following:
Angle B equals 90 degrees.
Is the triangle in the drawing a right triangle?
What kind of triangle is given here?
Since none of the sides have the same length, it is a scalene triangle.
Scalene triangle
Calculate the size of angle X given that the triangle is equilateral.
Remember that the sum of angles in a triangle is equal to 180.
In an equilateral triangle, all sides and all angles are equal to each other.
Therefore, we will calculate as follows:
We divide both sides by 3:
60
Given the values of the sides of a triangle, is it a triangle with different sides?
As is known, a scalene triangle is a triangle in which each side has a different length.
According to the given information, this is indeed a triangle where each side has a different length.
Yes
Choose the appropriate triangle according to the following:
Angle B equals 90 degrees.
Let's note in which of the triangles angle B forms a right angle, meaning an angle of 90 degrees.
In answers C+D, we can see that angle B is smaller than 90 degrees.
In answer A, it is equal to 90 degrees.
Is the triangle in the drawing a right triangle?
It can be seen that all angles in the given triangle are less than 90 degrees.
In a right-angled triangle, there needs to be one angle that equals 90 degrees
Since this condition is not met, the triangle is not a right-angled triangle.
No
Is the triangle in the drawing a right triangle?
In a right triangle, the sum of the two non-right angles is...?
What kind of triangle is the following
Given an equilateral triangle:
What is its perimeter?
Below is an equilateral triangle:
If the perimeter of the triangle is 33 cm, then what is the value of X?
Is the triangle in the drawing a right triangle?
Due to the presence of the 90 degree angle symbol we can determine that this is indeed a right-angled triangle.
Yes
In a right triangle, the sum of the two non-right angles is...?
In a right-angled triangle, there is one angle that equals 90 degrees, and the other two angles sum up to 180 degrees (sum of angles in a triangle)
Therefore, the sum of the two non-right angles is 90 degrees
90 degrees
What kind of triangle is the following
Since in the given triangle all angles are equal, all sides are also equal.
It is known that in an equilateral triangle the measure of the angles will always be equal to 60° since the sum of the angles in a triangle is 180 degrees:
Therefore, it is an equilateral triangle.
Equilateral triangle
Given an equilateral triangle:
What is its perimeter?
Since the triangle is equilateral, that is, all sides are equal to each other.
The perimeter of the triangle is equal to the sum of all sides together, the perimeter of the triangle in the drawing is equal to:
15
Below is an equilateral triangle:
If the perimeter of the triangle is 33 cm, then what is the value of X?
We know that in an equilateral triangle all sides are equal.
Therefore, if we know that one side is equal to X, then all sides are equal to X.
We know that the perimeter of the triangle is 33.
The perimeter of the triangle is equal to the sum of the sides together.
We replace the data:
We divide the two sections by 3:
