Triangle Congruence Criteria Test Review

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion that states if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion used specifically for right triangles, stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

Front

What is CPCTC?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent, a principle used after proving triangles are congruent to state that their corresponding parts are also congruent.

Front

When can you use the SSS criterion?

Back

You can use the SSS criterion when you know the lengths of all three sides of two triangles and want to prove they are congruent.

Front

When can you use the SAS criterion?

Back

You can use the SAS criterion when you know the lengths of two sides and the measure of the included angle of two triangles.

Front

When can you use the AAS criterion?

Back

You can use the AAS criterion when you know the measures of two angles and the length of one side of two triangles.

Front

When can you use the ASA criterion?

Back

You can use the ASA criterion when you know the measures of two angles and the length of the included side of two triangles.
