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

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)( x, y ) → ( -x, y )

Answer 1

The correct option that best describes the transformation is C: (x, y) → (x, -y) (x, y) → (x, -y). This rule reflects a reflection across the x-axis, which would transform trapezoid ABCD into triangle A՚B՚C՚D՚.
