Congruent Triangle Rules

Front

What does SAS stand for?

Back

SAS stands for Side-Angle-Side, a rule used to prove the congruence of triangles.

Front

Which segment is congruent to EF?

Back

The segment congruent to EF is GF.

Front

Name the postulate that makes the triangles congruent if two sides and the included angle are known.

Back

The postulate is SAS (Side-Angle-Side).

Front

State if the two triangles are congruent. If they are, state how you know.

Back

The triangles are congruent (Answer: B).

Front

If ∆PIG ≅ ∆COW, what is WO congruent to?

Back

WO is congruent to GI.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a rule stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What does ASA stand for in triangle congruence?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

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

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

How can you prove two triangles are congruent using the SSS postulate?

Back

You can prove two triangles are congruent using the SSS postulate by showing that all three sides of one triangle are equal to the three sides of another triangle.
