Question

Which algebraic representation of a transformation on a coordinate grid does NOT preserve congruence?

a.(x,y) > (-x, y)
b.(x,y) > (x+6, y+6)
c.(x,y) > (6x, 6y)
d.(x,y) > (-y, x)

Answer 1

c

Explanation:

answer a is a rotation which is a congruent trasformation

answer b is only moving the object not changing its size

answer d is the same as answer a

answer c is changing size
