Warmup on Congruent Triangles

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a method to prove triangles are congruent by showing two angles and the included side are equal.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method to prove triangles are congruent by showing all three sides are equal.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a method to prove triangles are congruent by showing two sides and the included angle are equal.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangles are congruent by showing two angles and a non-included side are equal.

Front

Is AAA a valid method for proving triangles congruent?

Back

No, AAA (Angle-Angle-Angle) does not prove triangles congruent as it only shows similarity, not congruence.

Front

Which method cannot be used to prove triangles are congruent?

Back

SSA (Side-Side-Angle) cannot be used to prove triangles are congruent.

Front

If two triangles have two angles and the included side equal, what can be concluded?

Back

The triangles are congruent by the ASA postulate.

Front

If two triangles have all three sides equal, what can be concluded?

Back

The triangles are congruent by the SSS postulate.

Front

If two triangles have two sides and the included angle equal, what can be concluded?

Back

The triangles are congruent by the SAS postulate.

Front

If two triangles have two angles and a non-included side equal, what can be concluded?

Back

The triangles are congruent by the AAS postulate.
