Congruent Triangles Review

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 that 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 method to prove triangles are congruent by showing that 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 method to prove triangles are congruent by showing that 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 method to prove triangles are congruent by showing that all three sides are equal.

Front

Which method is NOT a valid way to prove triangles are congruent?

Back

SSA (Side-Side-Angle) is NOT a valid method to prove triangles are congruent.

Front

What additional information is needed to prove triangles congruent by SAS?

Back

You need to show that the included side between the two angles is equal.

Front

What is the Reflexive Property in triangle congruence?

Back

The Reflexive Property states that a geometric figure is congruent to itself, which is often used in proofs.

Front

What is the Transitive Property in triangle congruence?

Back

The Transitive Property states that if triangle A is congruent to triangle B, and triangle B is congruent to triangle C, then triangle A is congruent to triangle C.

Front

What is the significance of congruent triangles in geometry?

Back

Congruent triangles have the same size and shape, which means their corresponding sides and angles are equal.

Front

How can you prove that two triangles are congruent using AAS?

Back

To prove triangles are congruent using AAS, show that two angles and a non-included side are equal.
