Triangle Congruence Review

Front

What are the criteria for triangle congruence?

Back

The criteria for triangle congruence are: SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg for right triangles).

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion used to prove that two triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion used to prove that two triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion used to prove that two triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion used to prove that two right triangles are congruent.

Front

What is CPCTC?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent, a principle used after proving triangles are congruent.

How do you determine if two triangles are congruent using ASA?

Back

To determine if two triangles are congruent using ASA, you need to show that two angles and the included side of one triangle are equal to the corresponding parts of the other triangle.

Front

How do you determine if two triangles are congruent using SAS?

Back

To determine if two triangles are congruent using SAS, you need to show that two sides and the included angle of one triangle are equal to the corresponding parts of the other triangle.

Front

How do you determine if two triangles are congruent using AAS?

Back

To determine if two triangles are congruent using AAS, you need to show that two angles and a non-included side of one triangle are equal to the corresponding parts of the other triangle.

What is the significance of 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 involving overlapping triangles.
