Rotational Symmetry

In your own words explain what rotational symmetry is.

Is when a shape can turn a shape a 360˚ angel

A shape has an order of rotational symmetry of 2. What does this mean?

How is rotational symmetry different from line symmetry?
Rotational symmetry is turning the shape and seeing if it fits. Line symmetry if folding the shape to see if its symmetrical

What do you do to check if a shape has rotational symmetry?
You put a pin in the middle then turn and see if it fits

Find pictures of 3 real life objects which have rotational symmetry (not shapes, objects e.g. foods, logos) and paste them into your post
