Not Similar

Front

What is the Side-Angle-Side (SAS) similarity theorem?

Back

If two sides of one triangle are proportional to two sides of another triangle and the included angles are congruent, then the triangles are similar.

Front

What is the Angle-Angle (AA) similarity theorem?

Back

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

Front

What is the Side-Side-Side (SSS) similarity theorem?

Back

If the corresponding sides of two triangles are proportional, then the triangles are similar.
