Today in math we've learned about rotation symmetry.
Rotation symmetry just means how many times a polygon fits onto its self to complete one rotation.
This flower can fit 9 times to its self.
Then we had to find the angle of rotation. Since it has 9 rotation symmetry, we have to divide it by 360 degrees. The reason why its 360 degrees is because the polygon used on the example above is fully turned which makes 360 degrees.
We then drew rotations on our graphs. The rotation can be clockwise or counter clockwise.
