State if the triangles in each pair are similar. If so, state how you know they are similar.

Are these two triangles similar? Which similarity criterion do you use to prove it?

Complete the similarity statement: △ADB ~ _______

The Angle-Angle Similarity (AA ~) Theorem states if two angles of one triangle are _______________ to two angles of another triangle, then the triangles are ____________________.

The Side-Side-Side Similarity (SSS ~) Theorem states if the corresponding sides of two triangles are _____________________, then the triangles are _________________.

The Side-Angle-Side Similarity (SAS ~) Theorem states that if two sides of one triangle are ________________ to two sides of another triangle and their _________________ angles are congruent, then the triangles are similar.

Which is not a similar triangle theorem?
