What is similarity in geometry?

Back

Similarity in geometry refers to figures that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are proportional.

What is the AA criterion for triangle similarity?

Back

The AA (Angle-Angle) criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.
