My work copy
When a ray of light is reflected from the light surface, the light strikes the surface at an angle( the angle of incidence) the is equal to the angle of reflection. Both of these angles are measured from a line that is perpendicular to the surface ( called the normal)
Using the diagram below, measure the total angle between each pair of incident and reflected rays in the left, middle and right rays. Then determine the angles of the reflection for each ray.
