Triangle Congruence

Front

What does AAS stand for in triangle congruence?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

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

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem used to prove that two triangles are congruent if all three sides of one triangle are equal to all three sides of another triangle.

Front

What does ASA stand for in triangle congruence?

Back

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

Front

What does AAS theorem require to prove triangle congruence?

Back

The AAS theorem requires two angles and the non-included side of one triangle to be equal to two angles and the non-included side of another triangle.

Front

What is the relationship between similar figures and their angles?

Back

Similar figures always have corresponding angles that are equal.

Front

What is the relationship between similar figures and their sides?

Back

Similar figures always have corresponding sides that are proportional.

Front

Which statement is NOT true about similar figures?

Back

B) Similar figures always have the same size.

Front

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

Back

The sides opposite those angles are proportional.

Front

How can you determine if two triangles are congruent using the SAS theorem?

Back

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.
