Practice Triangle Congruence

Front

What does AAS stand for in triangle congruence?

Back

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

What does ASA stand for in triangle congruence?

Back

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

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem used to prove triangle congruence when all three sides of one triangle are equal to the three sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem used to prove triangle congruence when two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What additional information is required for the 2 triangles to be congruent by SAS?

Back

The included angle between the two sides must be known.

Front

If two triangles have two angles equal, what can be said about their sides?

Back

The sides opposite the equal angles are proportional, but the triangles are not necessarily congruent without additional information.
