Question

Part a) using the rule (x,y) -> (x,-y) find the image points of x(1,4) and y(5,1)
Part b) on the same set of axes draw it shows xy with a line over it and x'y' with a line over it
Part c) show that xy is congruent to x'y'

Answer 1

so you need to find the distance from x to y and find the distance from x' to y'

Answer 2

if they have the same distance then they are congruent
