A circle, square, and a triangle all have rotational symmetry.

No, not all shapes have the same rotational symmetry as their order. The order of rotational symmetry refers to the number of times a shape can be rotated around a central point and still look the same within one full rotation (360 degrees). While some shapes like regular polygons have rotational symmetry that corresponds directly to their number of sides, irregular shapes may have a different order of symmetry, or none at all.
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
You can work out the rotation of shapes by identifying the transformations and the rotations.Ê The measurements of the rotation of shapes are expressed in degrees.
