Line of symmetry
- A line of symmetry of a polygon (shape) is a line which divides the shapes into two halves which are mirror images of each other.
Order of rotation
- The order of rotational symmetry of a polygon (shape) is the number of times you can rotate it and have it look exactly the same.
- This rectangle has an order of rotation of 2.
