Front

What is line symmetry?

Back

A shape has line symmetry if it can be divided into two identical halves that are mirror images of each other.

Front

Which shape has line symmetry?

Back

Front

What is rotational symmetry?

Back

A shape has rotational symmetry if it looks the same after a certain degree of rotation.

Front

What is the order of rotational symmetry?

Back

The order of rotational symmetry is the number of times a shape fits onto itself during a full rotation (360 degrees).

Front

What is a tessellation?

Back

A tessellation is a pattern made of one or more shapes that fit together without any gaps or overlaps.
