Question

triangle JKL has vertices J(3,-7) K(7,-3) and L(3,6) What are the cordinates of point J after a 270° rotation counterclockwise about the orgin?

Answer 1

(-7, -3)

Explanation:

• 270° counterclockwise rotation is the same as a 90° clockwise rotation
• If the point J (3, -7) is rotated 90° clockwise,
• ⇒ Point J' = (-7, -3)
