Pleasseee hellppp 20 points will be ! 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
