Rotational symmetry is a shape that can be turned around in a 360 degree and in that rotation the shape will match itself.
A shape has an order of rotational symmetry of 2. What does this mean?
This means that the shape has matched it self 2 times in the 360 rotation. That means the shape has rotational symmetry.
How is rotational symmetry different from line symmetry?
Line symmetry doesn't rotate, there is a line that separates the picture in half to see if they are the same on both sides. rotational symmetry rotates the picture in a 360 degree which sees if it can match it self during the 360 rotation.
What do you do to check if a shape has rotational symmetry?
Rotate the picture at 360. If it matches itself it has rotational symmetry.
