Front

Which triangle congruence theorem can be used to prove the triangles are congruent?

Back

SSS (Side-Side-Side) theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

Which of the following is NOT a triangle congruence theorem?

Back

AAA (Angle-Angle-Angle) is not a congruence theorem because it does not guarantee that the triangles are congruent; it only shows that they are similar.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem 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 theorem 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.
