Triangle Similarity Theorems Practice

Front

What is the AA similarity criterion?

Back

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

What does the SAS similarity criterion state?

Back

The SAS (Side-Angle-Side) similarity criterion states that 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.

What is the significance of the Corresponding Angle Postulate?

Back

The Corresponding Angle Postulate states that if two parallel lines are cut by a transversal, then each pair of corresponding angles is congruent.

What is the AAS similarity criterion?

Back

The AAS (Angle-Angle-Side) similarity criterion states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are similar.

What is the Embedded Triangles Property?

Back

The Embedded Triangles Property states that if a triangle is formed within another triangle, the angles of the embedded triangle are related to the angles of the larger triangle.

How do you determine if triangles are not similar?

Back

Triangles are not similar if their corresponding angles are not congruent or their corresponding sides are not in proportion.
