Aim and shoot on a 3D billiard table laid on the coordinate plane so that the ball bounces off a cushion and hits the target ball. Turn on the mirror ball to see B(a, b) reflected in the cushion line beyond the cushion: aiming straight at it gives the bent path to B (x-axis, y-axis, two cushions, and a wall on the line y = x).
Key conceptsreflection · reflection in the x-axis · reflection in the y-axis · reflection in the origin · reflection in the line y = x · coordinate plane · angle of incidence and reflection
