Back

Altitudes.

Front

What is an altitude in a triangle?

Back

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

Front

What is a median in a triangle?

Back

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

Front

What is a perpendicular bisector?

Back

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

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal angles.

Front

How many altitudes can be drawn in a triangle?

Back

Three altitudes, one from each vertex.

Front

How many medians can be drawn in a triangle?

Back

Three medians, one from each vertex to the midpoint of the opposite side.
