Trapezoid ABCD was transformed to create triangle A՚B՚C՚D՚.

Question

Which rule best describes this transformation?
Responses
A (x, y) → (-x, -y)( x, y ) → ( -x, -y )
B (x, y) → (-y -x)( x, y ) → ( -y -x )
C (x, y) → (x, -y)( x, y ) → ( x, -y )
D (x, y) → (-x, y)??

Answer 1

The correct answer is C (x, y) → (x, -y). This rule describes a reflection over the x-axis, which would transform trapezoid ABCD to triangle A'B'C'D' with the vertices in the same order.
