Congruent Triangles Practice

Front

What are congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the symbol used to denote congruence between triangles?

Back

The symbol for congruence is '≅'. For example, if triangle ABC is congruent to triangle DEF, it is written as ΔABC ≅ ΔDEF.

Front

What is the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) theorem?

Back

The CPCTC theorem states that if two triangles are congruent, then their corresponding parts (sides and angles) are also congruent.

Front

What is the Angle-Side-Angle (ASA) congruence criterion?

Back

The ASA criterion states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) congruence criterion?

Back

The SAS criterion states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

The SSS criterion states that if all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

Front

How do you identify corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are the angles that are in the same relative position in each triangle.

Front

How do you identify corresponding sides in congruent triangles?

Back

Corresponding sides in congruent triangles are the sides that are in the same relative position in each triangle.

Front

What is the definition of a corresponding side?

Back

A corresponding side is a side of one triangle that matches in length with a side of another triangle in a pair of congruent triangles.

Front

What is the definition of a corresponding angle?

Back

A corresponding angle is an angle of one triangle that matches in measure with an angle of another triangle in a pair of congruent triangles.
