Geo 5.2 AAS, SAS, SSS, ASA

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 are equal.

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 a non-included side are equal.

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 are equal.

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 are equal.

Front

Which triangle congruence theorem is NOT valid?

Back

SSA (Side-Side-Angle) is not a valid theorem for proving triangle congruence.

Front

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

Back

The two triangles are congruent by the ASA theorem.

Front

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

Back

The two triangles are congruent by the AAS theorem.

Front

What is the significance of the included side in the SAS theorem?

Back

The included side is the side between the two angles being compared; it must be equal for the triangles to be congruent.

Front

Can two triangles be congruent if only two sides are equal?

Back

Not necessarily; you need to know the included angle or use another congruence theorem.

Front

What is a congruence statement?

Back

A congruence statement indicates that two triangles are congruent and lists corresponding parts, such as angles and sides.
