Rotate the rectangle ABCD 90° clockwise about the point (0,-1). Each corner of the image A'B'C'D' is the same distance from the centre of rotation as the original shape.

Consider the mechanism shown below made up of moveable links AB, BD and slider D. Link AB is rotating CCW at a constant rate. Point C is the center of rotation for BD, where point C is at the ...
