Similar Triangle Postulates Quiz

What does the AA Similarity Postulate state?

• Two triangles are similar if two angles of one triangle are congruent to two angles of another triangle.

• Two triangles are similar if all their sides are proportional.

• Two triangles are similar if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal.

• Two triangles are similar if their corresponding sides are equal in length.
