Line and Rotational Symmetry

Front

What is line symmetry?

Back

Line symmetry occurs when a shape can be divided into two identical halves by a line (or lines) such that one half is a mirror image of the other.

Front

What is rotational symmetry?

Back

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