The image of each point in the pre-image can be obtained by drawing a perpendicular from the point to the line and then doubling its length.

because that's the rule. angle of incident ALWAYS = angle of reflection.
You can change the first or second point to its oppisite
When a light ray hits a surface at an angle (called the angle of incidence) and all or part of it is reflected at an angle (called the angle of reflection), the law of reflection states: the angle of reflection equals the angle of incidence. The angle is measured from an imaginary line drawn perpendicular to the surface at the point the ray hits the surface. what the hecka i dont understand this crap i hate math
reflection
Reflection off of rough surfaces is called a perkokepuw.
