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.

Front

What does the Reflexive Property state in geometry?

Back

Front

What is the SSS similarity criterion?

Back

The SSS (Side-Side-Side) similarity criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the SAS similarity criterion?

Back

The SAS (Side-Angle-Side) similarity criterion states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are congruent, then the triangles are similar.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

How can you determine if two triangles are similar?

Back

You can determine if two triangles are similar by using the AA, SAS, or SSS similarity criteria.

Front

What is the Embedded Triangles Property?

Back

The Embedded Triangles Property states that if one triangle is inside another and the angles are congruent, the triangles are similar.

Front

What is 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.

Front

What does it mean for triangles to be similar?

Back

Triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the significance of the AA similarity criterion?

Back

The AA similarity criterion is significant because it provides a quick way to prove triangle similarity using only angle measures.
