b) kβ(6, 4); lβ(3, 3)
step-by-step explanation:
a 270Β° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)
this means the endpoints of the side congruent to kl, k' and l', would be mapped as:
k'(-4, 6)β(6, 4)
l'(-3, 3)β(3, 3)
