We say a shape has ROTATIONAL SYMMETRY if it fits exactly into itself (looks exactly THE SAME) when it is rotated. TOP How many times does this shape fit into We say it has rotational symmetry of order 4 itself?
A shape may have NO Rotational Symmetry A shape is said to have NO Rotational Symmetry If it fits onto itself only ONE TIME
The ORDER of Rotational Symmetry • The order of rotational symmetry of a shape is determined by how many times the shape fits onto itself during a 360° turn.

Regular Polygons What did we say a Regular Polygon is? A regular polygon is a shape which has: • All sides equal • All angles equal Examples ? What did we say about lines of symmetry in regular polygons? Regular polygons have lines of symmetry equal to the number of sides/angles that they have
What can we also conclude? Regular polygons have order of rotational symmetry equal to the number of sides/angles that they have. For REGULAR POLYGONS No. of sides No. of angles Lines of symmetr y Order
