Copy each figure on graph paper. Then draw the image by reflection in line k.

In the two-wall shot illustrated at the right, a reflection in one wall maps H to , and a reflection in a second wall (extended) maps to . To roll the ball from B to H, you aim for . Show that the total distance travelled by the ball equals the distance .

Complete the following. Assume points D, C, U, W, X, and Y are obtained by reflection in link k or j.

Sketch each figure on the chalkboard. With a different color, sketch its image, using the dashed line as the line of reflection.
