What is the definition of a midpoint?

Back

A midpoint is a point that divides a line segment into two equal parts.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.
