Front

What is the definition of similar figures in geometry?

Back

Similar figures have the same shape but not necessarily the same size; their corresponding sides are proportional.

Front

What does the AA similarity criterion state?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.
