Question

Triangle XYZ with vertices X(0, 0), Y(0, –2), and Z(–2, –2) is rotated to create the image triangle X'(0, 0),
Y'(2, 0), and Z'(2, –2).

Which rules could describe the rotation? Select two options.

R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (y, –x)

Answer 1

Answer: R0, 90°, (x, y) → (–y, x)

Step-by-step explanation:

If we consider Y(0,-2) mapping onto Y(2,0), we know that this was a rotation 90 degrees about the origin.

Answer 2

Answers:

A ... R0, 90°

D ... (x, y) → (–y, x)
