Two Rotations = One New Rotation

Please enable Java for an interactive construction (with Cinderella).

You can change the red center of rotation by dragging. The two angles of the successive rotations can be changed by dragging the yellow and green vectors. The original position, size and orientation of the white AO symbol can be changed with the two red points on it.


Soli Deo Gloria. Created with Cinderella by Eckhard Hitzer (Fukui).
