Question

Find the coordinates of S' after a rotation of the triangle 180° about the origin​

Answer 1

Answer: b) (4, -4)

Explanation:

Rotation of 180°: (x, y) → (y, x)

S = (-4, 4) → S' = (4, -4)

Note: If you graph the point and then turn the graphing board 2 turns to the left, it will visually show you where the point lands after a 180° rotation.
