Reflectional and Rotational Symmetry

Front

What is reflectional symmetry?

Back

Reflectional symmetry, also known as line symmetry, occurs when one half of an object is a mirror image of the other half.

Front

What is rotational symmetry?

Back

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