Identify the reflection rule on a coordinate plane that verifies that triangle a(-2,3), b(-3,-2), c(-10,0) and triangle a'(2,3), b'(3,-2), c'(10,0) are congruent when reflected over the y-axis.

a) (x, y) → (-x, -y)

b) (x, y) → (x, -y)

c) (x, y) → (-x, y)

d) the triangles are not congruent

pleeease answer i need this asap! 15 points!
