Congruent Triangles Review

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does SAS stand for in triangle congruence?

Back

Side-Angle-Side: A criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

Angle-Angle-Side: A criterion for triangle congruence where two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle: A criterion for triangle congruence where two angles and the included side of one triangle are equal to two angles and the corresponding included side of another triangle.

Front

What is the SSS criterion for triangle congruence?

Back

Side-Side-Side: A criterion for triangle congruence where all three sides of one triangle are equal to all three sides of another triangle.

Front

Which triangle congruence criterion is not valid?

Back

SSA (Side-Side-Angle) is not a valid criterion for proving triangle congruence.

Front

If two triangles have two angles and the non-included side equal, what can be concluded?

Back

The triangles are congruent by AAS.

Front

If two triangles have two sides and the included angle equal, what can be concluded?

Back

The triangles are congruent by SAS.

Front

What is the relationship between corresponding parts of congruent triangles?

Back

Corresponding parts of congruent triangles are equal.

Front

How can you prove that two triangles are congruent using the AAS criterion?

Back

Show that two angles and a non-included side of one triangle are equal to the corresponding parts of another triangle.
