Triangle Congruency

Front

What information is required to prove triangles are congruent?

Back

At least one of the following: SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), or HL (Hypotenuse-Leg for right triangles).

Front

Which of the following is a triangle congruency theorem?

Back

ASA (Angle-Side-Angle) is a triangle congruency theorem.

Front

Which segment is congruent to EF?

Back

GF is congruent to EF.

Front

What is the postulate that makes triangles congruent if two sides and the included angle are known?

Back

SAS (Side-Angle-Side) postulate.

Front

How can you determine if two triangles are congruent?

Back

By using the Angle-Side-Angle (ASA) criterion.

Front

What does SSS stand for in triangle congruency?

Back

SSS stands for Side-Side-Side, which states 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 congruency?

Back

ASA stands for Angle-Side-Angle, which states 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 congruency?

Back

AAS stands for Angle-Angle-Side, which states 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 Hypotenuse-Leg (HL) theorem?

Back

The HL theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

Front

What is the difference between AAA and other congruency criteria?

Back

AAA (Angle-Angle-Angle) does not prove congruency; it only proves similarity.
