PLEASE HELP?!!

Triangle XYZ has its vertices at the following coordinates:

X(2, 1) Y(4,-1) Z(1,-3)

Give the coordinates of the image triangle X'Y'Z' after a 90° counterclockwise rotation about the origin.

Answer :

ferrybukantoro

Step-by-step explanation:

after a 90° counterclockwise rotation about the origin =>

X(a, b) => X'(-b, a)

so,

X(2, 1) => X'(-1, 2)

Y(4, -1) => Y'(1, 4)

Z(1, -3) => Z'(3, 1)
