SSS, SAS, ASA, AAS

Front

What does SSS stand for in triangle congruence?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

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

Front

What does ASA stand for in triangle congruence?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

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

Front

Which postulate cannot be used to prove triangles congruent?

Back

AAA (Angle-Angle-Angle) cannot be used to prove triangles congruent because it does not provide information about the sides.

Front

If two triangles have two equal angles and one equal side, what postulate can be used to prove they are congruent?

Back

AAS (Angle-Angle-Side) can be used to prove the triangles are congruent.

Front

If two triangles have two sides and the included angle equal, which postulate applies?

Back

SAS (Side-Angle-Side) applies to prove the triangles are congruent.

Front

What is the relationship between the angles in congruent triangles?

Back

In congruent triangles, corresponding angles are equal.

Front

If triangle ABC is congruent to triangle DEF, what can be said about their corresponding sides?

Back

The corresponding sides of triangle ABC and triangle DEF are equal in length.

Front

How can you prove that two triangles are congruent using the SSS postulate?

Back

By showing that all three sides of one triangle are equal to all three sides of another triangle.
