4 cm, Sem, 6 cm
10 mm, 2.emm, 30 mm
Set 4
Set 3
10 mm, 20 mm, 30 mm
12 t. Se f. 2017
12 ft, 16 ft, 20 ft

no one knows lol

step-by-step explanation:

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)
