What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem used to prove triangles are congruent when two angles and the non-included side are known.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem used to prove triangles are congruent when two sides and the included angle are known.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem used to prove triangles are congruent when all three sides are known.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem used to prove triangles are congruent when two angles and the included side are known.

Front

Can you use SAS or AAS or both to prove the triangles congruent?

Back

AAS only.

Front

Which triangle congruence theorem can be used to prove the triangles are congruent if all three sides are known?

Back

SSS.

Front

Which triangle congruence theorem can be used to prove the triangles are congruent if two sides and the included angle are known?

Back

SAS.

Front

If two angles of one triangle are equal to two angles of another triangle, what can be concluded?

Back

The triangles are congruent (AAS theorem).

Front

If two sides and a non-included angle of one triangle are equal to two sides and a non-included angle of another triangle, what can be concluded?

Back

The triangles are not necessarily congruent (not a valid theorem).

Front

What is the relationship between congruent triangles?

Back

Congruent triangles have the same size and shape, meaning all corresponding sides and angles are equal.
