[b][color=#38761d]Rotational Symmetry[/color][/b] occurs when a shape can be rotated to land back on top of itself. Knowing whether or not quadrilaterals have rotational symmetry in important when reasoning about their attributes.[br][br][b][color=#38761d]Rotations are Defined by a center and an angle.[br][/color][/b]The quadrilaterals below have the center of rotation identified already. Use the slider (Red Point) to rotate the quadrilaterals and find the angle of rotational symmetry for each.
