Plz help. Only answer if you know. Find the length of each side of the triangle to determine the classification. A(1,0), B(1,8), C(5,4).
1. AB =
2. BC =
3. AC =
4. Type of triangle

yes ok                                            

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)
