Which value can you use for n to show that the first step in a proof by mathematical induction of "For all the positive integers n, 1^2+2^2+...+n^2=n(n+1)(2n+1)/6 " is true? a. n = 3.26
b. n = 1/4
c. n = 1
d. n = -10.1

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)
