AAABBBCCCDDDEEEFFF

Step-by-Step Solution

To solve the problem of identifying to which side of triangle ABC ABC the median and the altitude are drawn, let's analyze the diagram given for triangle ABC ABC .

  • We acknowledge that a median is a line segment drawn from a vertex to the midpoint of the opposite side. An altitude is a line segment drawn from a vertex perpendicular to the opposite side.
  • Upon reviewing the diagram of triangle ABC ABC , line segment AD AD is a reference term. It appears to meet point C C in the middle, suggesting it's a median, but it also forms right angles suggesting it is an altitude.
  • Given the placement and orientation of AD AD , it is perpendicular to line BC BC (the opposite base for the median from A A ). Therefore, this line is both the median and the altitude to side BC BC .

Thus, the side to which both the median and the altitude are drawn is BC.

Therefore, the correct answer to the problem is the side BC BC , corresponding with choice Option 2: BC \text{Option 2: BC} .

Answer

BC

Exercise #2

Look at the triangle below.

Which side is the height and which side is the median?

AAABBBCCCDDD

Video Solution

Step-by-Step Solution

To solve this problem, we need to analyze the roles of line segment DC in the triangle ABC:

  • Step 1: Identify if DC is a height
    A height (altitude) is a line segment from a vertex perpendicular to the opposite side. The image suggests that line DC is vertical, with apparent perpendicularity to BC due to the presence of D near the center of the triangle, making DC a plausible height.

  • Step 2: Identify if DC is the median
    A median divides the opposite side into two equal lengths, from a vertex. Without explicit symmetry in the image, but assuming graphic accuracy and typical diagram problems, DC can be a median if D is the midpoint.

  • Step 3: Confirm if DC is both a height and a median
    In instances such as isosceles or equilateral triangles, a segment can be both. Given D’s position and symmetric considerations from vertex A, it's likely DC is both here.

Thus, line segment DC is both the median and the height.

Therefore, the correct answer is DC = median and height.

Answer

DC = median and height

Exercise #3

ABC is a triangle.

To which of its sides are the height and the median drawn?

AAABBBCCCXX

Video Solution

Step-by-Step Solution

To determine which side has both the height and median, let's examine the geometric definitions and their implications in a triangle:

  • A height (altitude) is a perpendicular line from a vertex to the opposite side, possibly extending outside the triangle if it's obtuse.
  • A median connects a vertex to the midpoint of the opposite side.

Both a median and height coincide on the same side only under specific symmetrical conditions, such as when the triangle is isosceles (with that side as the base) or when the altitude divides it symmetrically.

In the given problem, since the components align such that both structures exist on the 'base' of symmetry (where the perpendicular bisects and equalizes), hence an educated assumption goes to the side 'AB'.

Thus, the side upon which both the height and the median are drawn is AB \text{AB} .

Answer

AB

Exercise #4

Which side of triangle ABC is both the median and the height drawn to?

CCCAAABBBDDDEEEFFF

Video Solution

Step-by-Step Solution

To solve this problem, we need to use the properties of medians and heights, specifically in isosceles triangles. In an isosceles triangle, the median from the vertex angle to the base is also the height. In the diagram of triangle ABC, given the problem context and a typical configuration of an isosceles triangle, we can see that:

  • The side AB is horizontally aligned in the diagram.
  • The point D, directly below A, suggests that the median from A also serves as the height to the base BC, if AB = BC making triangle ABC isosceles.

Therefore, in triangle ABC, side AB is both the median and the height of the triangle, assuming a vertical symmetry along median AD, characteristic of an isosceles triangle configuration.

Therefore, the correct answer is AB AB .

Answer

AB

Exercise #5

The triangle ABC is shown below.

To which side are the median and the altitude drawn?

AAABBBCCCDDDEEE

Video Solution

Step-by-Step Solution

In the problem of determining which side of triangle ABC has a median and an altitude drawn, we begin by understanding the role of these geometric features:

Medians: A median originates from one vertex and connects to the midpoint of the opposing side. Therefore, it must appear as a line bisecting opposite side.

Altitudes: An altitude also starts from a vertex but descends perpendicularly to the opposite side, forming a right angle.

In exploring the labels and positional intersection lines on the provided diagram, if available, we do not find a clear depiction through the labels and positions alone, which allows us to exactly pinpoint a side being bisected or with a right angle from a vertex. The problem declaratively assures no qualification dominantly demonstrating altitude (notably not perpendicular) or median (not clearly bisecting any side).

Thus, the correct choice and conclusion is that neither is correctly shown in respecting any side of the triangle ABC.

Therefore, no side of triangle ABC has a defined median and altitude drawn distinctly according to known geometric properties and referential diagram analysis.

No side

Answer

No side

Exercise #6

ABC is a triangle.

Which of the lines is the height and which is the median?

AAABBBCCCDDDEEEXX

Video Solution

Step-by-Step Solution

To solve this problem, we need to correctly identify the height and median in the triangle ABC ABC .

  • Step 1: Understand the Definitions
    The height (or altitude) from a vertex of a triangle is a segment that is perpendicular to the line containing the opposite side. The median from a vertex is a segment that joins the vertex to the midpoint of the opposite side.
  • Step 2: Apply Definitions to Diagram
    - Line AB AB connects vertex A A to vertex B B , forming a perpendicular segment to base BC BC . Hence, it is a height.
    - Line EB EB connects vertex A A to point E E , the midpoint, dividing segment BC BC into two equal parts, thus acting as a median.
  • Step 3: Match to Answer Choices
    Having sorted the segments as the height and the median, match our findings to the provided choices. The choice indicating that BC+AB BC + AB is the height and EB EB is the median is correct.

Therefore, the solution to the problem is BC+AB= BC + AB = height, EB= EB = median.

Answer

BC + AB = height,

EB = median

Exercise #7

Look at the triangle in the diagram below.

To which side is the median and the height drawn?

AAABBBCCCDDDEEE

Video Solution

Step-by-Step Solution

To solve this problem, we'll observe features of the diagram and follow these steps:

  • Step 1: Inspect the lines depicted in the triangle from the diagram.
  • Step 2: Define geometric terms: median and height.
  • Step 3: Identify which side of the triangle these lines reference.

Now, let's apply these steps:
Step 1: The diagram shows triangle ABC ABC with a line drawn from point A A to the base BC BC . Note that there is an apparent point E E where this line intersects BC BC perpendicularly.
Step 2: The line AE AE can be considered both the height and the median:

  • As a height, AE AE is perpendicular to the base BC BC .
  • For the median, this line also bisects the segment BC BC at point E E , showing it divides opposite side BC BC into two equal halves, hence making it the midpoint. This confirms the secondary condition of being a median.

Step 3: Conclude that line AE AE acts on the side BC BC as evidenced by its perpendicular nature and midpoint bisecting property from the diagram.

Therefore, the solution to the problem is that both the median and the height are drawn to side BC BC .

Answer

BC

Exercise #8

The triangle ABC is shown below.

Which side or sides are the height and the median drawn to?


AAABBBCCCDDDEEEFFF

Video Solution

Step-by-Step Solution

To solve this problem, we'll verify which side or sides have the height and the median based on their definitions.

First, we identify what constitutes a height in the triangle. A height, or an altitude, is a perpendicular line segment from one vertex to the opposite side or its extension. In many triangles, this is represented by a line that intersects at a right angle with the side it is drawn to.

The median of a triangle is a line segment drawn from a vertex to the midpoint of the opposite side. It divides the opposite side into two equal parts.

Now, we'll analyze the given diagram:

  • Examine the triangle ABC and any drawn perpendicular lines that represent heights.
  • Check for lines that extend from a vertex and bisect the opposite side, indicating medians.

Upon reviewing the diagram, there appear to be no segments that are clearly perpendicular from a vertex to the opposite side, suggesting no height is drawn. Similarly, there is no indication of a line from a vertex bisecting the opposite side, suggesting no median is concretely drawn either.

Therefore, based on this analysis, we conclude that no sides have the height or median explicitly drawn to them in this diagram.

The correct choice, given this information, is: No sides.

Answer

No sides
