Back

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

Front

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

Identify the segment that connects the midpoints of two sides of a triangle.

Back

This segment is called a midsegment.

Front

Front

What is the difference between a median and an altitude?

Back

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