Congruent Triangles

Front

What is the Angle-Angle-Angle (AAA) criterion for triangle congruence?

Back

AAA is not a valid criterion for proving triangles congruent because it only shows that triangles are similar, not congruent.

Front

If ∠A ≅ ∠D, what can be inferred about these angles?

Back

Angles A and D are congruent, meaning they have the same measure.

Front

Given ∆EHG≅∆KFC, which sides or angles are congruent?

Back

EG≅KC is a true statement based on the congruence of the triangles.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a valid criterion for proving triangle congruence.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a valid criterion for proving triangle congruence.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a valid criterion for proving triangle congruence.

Front

Why is AAA not a valid reason for proving triangle congruence?

Back

AAA only indicates similarity, not congruence, as it does not provide information about the sides.

Front

What is the SSA condition in triangle congruence?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for proving triangle congruence.

Front

What is the AAS criterion in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a valid criterion for proving triangle congruence.

Front

What is the relationship between congruent triangles?

Back

Congruent triangles have equal corresponding sides and angles.
