answer?
angle of incidence is always equal to angle of reflection |i| = |r|
What evidences?
from the data collected of table of angle of incidence∠i and angle of reflection ∠r with the normal line to the plane of the mirror surface.
No.

Modeling Activity:
if the x-y axes passes through the mirror at the point of light ray, what is a possible model for ∠i = 45 ° in terms of mathematics using x and y ?Answer: x = +y and -y for vertical mirror
Answer: y = |x| or y = abs(x) for horizontal mirror
Need to fix bug
