(a) Reflect the r-shape (Fig. 5.1.6) about the x-axis and then about the y-axis.

Find the transformation matrix
M = RyRx.
Where Rx is the matrix for reflection about the x-axis and Ry is the matrix for reflection about the y-axis, and sketch the transformed r-shape.
(b) What counterclockwise rotation is equivalent to these successive reflections? Illustrate with a sketch.
