G-5.3 2024-Medians, altitudes, angle bisectors, and ∟ bisectors

Front

What is a perpendicular bisector?

Back

A line segment that divides another line segment into two equal parts at a 90-degree angle.

Front

Identify the altitude of a triangle.

Back

A line segment from a vertex to the opposite side, forming a right angle with that side.

Front

What is a median in a triangle?

Back

A line segment from a vertex to the midpoint of the opposite side.

Front

Define an angle bisector.

Back

A line segment that divides an angle into two equal angles.

Front

What is the relationship between a median and the sides of a triangle?

Back

A median connects a vertex to the midpoint of the opposite side.

Front

How do you identify a perpendicular bisector in a triangle?

Back

It is the line segment that is perpendicular to a side and divides it into two equal lengths.

Front

What is the significance of an altitude in a triangle?

Back

It helps in calculating the area of the triangle.

Front

Can a median be an altitude?

Back

Yes, if the triangle is isosceles, the median from the vertex angle is also an altitude.

Front

What is the difference between an angle bisector and a median?

Back

An angle bisector divides an angle, while a median divides a side.

Front

How many medians does a triangle have?

Back

A triangle has three medians, one from each vertex.
