A light directed from point
If
measures , find the measures of , , , , and . When the light hits the mirror the angle of incidence and angle of reflection are congruent. Therefore
, , , , Why must the arrows at points
and be parallel? Use the angle measurements found to explain why the arrows at points
and must be parallel.
