7.1/7.2 Congruent Figures Practice

Front

What are congruent figures?

Back

Congruent figures are shapes that are identical in form and size. They can be superimposed on each other through rotations, translations, or reflections.

What does the symbol '≅' represent in geometry?

Back

The symbol '≅' indicates that two angles or segments are congruent.

What is the significance of the congruence of segments in geometric proofs?

Back

The congruence of segments is crucial in geometric proofs as it allows for the establishment of equality between lengths, which can be used to prove other properties and relationships.

Front

How can you determine if two angles are congruent?

Back

Two angles are congruent if they have the same measure, which can be verified using a protractor or by comparing them to a known angle.

Front

What is a congruence transformation?

Back

A congruence transformation is a movement of a figure in the plane that preserves its size and shape, including translations, rotations, and reflections.

Front

What is the relationship between congruent triangles and their corresponding parts?

Back

In congruent triangles, all corresponding parts (sides and angles) are equal, which is known as the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) principle.

Front

What is the SSS Congruence Postulate?

Back

The SSS (Side-Side-Side) Congruence Postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the SAS Congruence Postulate?

Back

The SAS (Side-Angle-Side) Congruence Postulate 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.
