Front

What is an angle bisector?

Back

A segment that divides an angle into two equal angles.

Front

What is a median in a triangle?

Back

A segment that connects a vertex to the midpoint of the opposite side.

Front

What is an altitude in a triangle?

Back

A segment from a vertex perpendicular to the line containing the opposite side.

Front

Which type of line does NOT have to go through the vertex of a triangle?

Back

Perpendicular bisectors.

Front

What is the relationship between the angle bisector and the angles it divides?

Back

It creates two angles that are equal in measure.

Front

How do you find the length of a segment in a triangle?

Back

Use the properties of triangles and theorems such as the Pythagorean theorem.

Front

What is the significance of the median in a triangle?

Back

It helps in finding the center of mass (centroid) of the triangle.

Front

What is the difference between an altitude and a median?

Back

An altitude is perpendicular to the opposite side, while a median connects a vertex to the midpoint of the opposite side.

Front

How can you identify an altitude in a triangle?

Back

Look for a segment that forms a right angle with the opposite side.
