What is symmetry?

Back

Symmetry is when a shape can be divided into two identical halves that are mirror images of each other.

Front

What is a line of symmetry?

Back

A line of symmetry is an imaginary line that divides a shape into two equal parts that are mirror images.

Back

An irregular shape, such as a scalene triangle, has no lines of symmetry.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same at certain angles.
