Plot each point and form the triangle abc. verify that the triangle is a right triangle. find its area,
a=(-5,3); b+(6,0); c=(5,5)

i agree because i see the other persons thinking is clear

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° 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)→(6, 4)

l'(-3, 3)→(3, 3)

i’m sorry but i don’t know sorry

answer: (3,11) is your answer.
