Rotations

Rotating an object in the plane means turning it around a center by a certain angle. Each point rotates on its own circle. Move the slider to change the angle of rotation. Move point A to change the center of rotation. Move points B, C, D, E to change the shape of the quadrilateral. The checkboxes let you show the circles and angle for each vertex.
