In this Demonstration you can rotate a square, a triangle, or the letter L about the point in the plane, choosing the coordinates with the "translation by " sliders or by dragging the point in the graphic. Change the angle to see the rotation about the point . The matrix of the rotation is given by the product of three operations (from right to left): translation by , rotation around the origin, and translation back by .
