Front

What is the definition of line symmetry?

Back

Line symmetry occurs when a figure can be divided into two identical halves that are mirror images of each other.

Front

What is rotational symmetry?

Back

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