CHECK Congruent Figures and Lines of Symmetry

Front

What are congruent figures?

Back

Congruent figures are shapes that are identical in shape and size. They can be rotated, reflected, or translated, but they remain the same size and shape.

Front

What is a line of symmetry?

Back

A line of symmetry is an imaginary line that divides a shape into two identical halves that are mirror images of each other.

Front

How can you determine if two figures are congruent?

Back

Two figures are congruent if all corresponding sides and angles are equal.

Front

What is the measure of angle M if Figure KLMN is congruent to Figure WXYZ and angle W is 85°?

Back

Angle M measures 85°.

Front

How many lines of symmetry does a square have?

Back

A square has 4 lines of symmetry.

Front

How many lines of symmetry does a circle have?

Back

A circle has an infinite number of lines of symmetry.

Front

What is the relationship between congruent shapes and their angles?

Back

Congruent shapes have equal corresponding angles.

Front

If a triangle has angles measuring 60°, 60°, and 60°, how many lines of symmetry does it have?

Back

An equilateral triangle has 3 lines of symmetry.

Front

What is the measure of angle M if angle N in a congruent figure is 95°?

Back

Angle M measures 95°.
