6.6 Congruent Triangles Test Review

Front

What does ASA stand for in triangle congruence?

Back

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

Front

What is the HL theorem in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a theorem that states if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and leg of another right triangle, then the triangles are congruent.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two different parallel lines cut by a transversal.

Front

If ∆LMK ≅ ∆LMT, what can we conclude about ∠K?

Back

∠K ≅ ∠T, meaning angle K in triangle LMK is congruent to angle T in triangle LMT.

Front

What does SSS stand for in triangle congruence?

Back

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

Front

What is the difference between ASA and AAS?

Back

ASA (Angle-Side-Angle) requires two angles and the included side, while AAS (Angle-Angle-Side) requires two angles and a non-included side.

Front

What does SSA stand for, and why is it not a congruence criterion?

Back

SSA stands for Side-Side-Angle, but it is not a congruence criterion because it does not guarantee that two 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

What is the purpose of triangle congruence postulates?

Back

Triangle congruence postulates are used to determine if two triangles are congruent based on specific criteria involving their sides and angles.

Front

What is the significance of the included angle in the ASA postulate?

Back

The included angle in the ASA postulate is the angle formed between the two sides that are being considered for congruence.
