Which reflection rule, if any, can be used to prove that rectangle a(-8, -3), b(-2, -3), c(-2, -6), d(-8, -6) and rectangle a'(8, -3), b'(2, -3), c'(2, -6), d'(8, -6) are congruent? a) (x, y) → (-x, y) b) (x, y) → (x, -y) c) (x, y) → (-x, -y) d) the rectangles are not congruent.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

-1/2 +2
