Question

What is the algebraic rule for a figure that is rotated 270 ° clockwise about the origen?

Answer 1

Each quadrants' angle is 90 degrees.

Rotating (x, y) -270 degrees would move it from quadrant I to quadrant IV.

(x, y) = (+, +) = Quadrant I
(-x, y) = (-, +) = Quadrant II
(-x, -y) = (-, -) = Quadrant III
(x, -y) = (+, -) = Quadrant IV

Answer 2

hope this help

Answer 3

X = x cos(270) - y sin(270)
Y = x sin(270) + y cos(270)


X = 0 + y
Y = -x + 0

say the point (5,6) it rotates to the point (6,-5)
