PLEASE CORRECT MY ANSWERS!!!!! MEDAL AND FAN!!!!!

17. The vertices of a polygon are given. Name the coordinates of the vertices of the image after a counterclockwise rotation of the given number of degrees about the origin.

J(-2,1), K(-1,4), L(3,4), M(3,1); 90° (Counterclockwise)


18. The vertices of a polygon are given. Name the coordinates of the vertices of the image after a counterclockwise rotation of the given number of degrees about the origin.

D(1,-4), E(2,0), F(5,-2); 270° (Counter-clockwise)

Answer 1

17. J (-1,-2)
K (-4,-1)
L (4,3)
M (1,3)

Answer 2

Answer 3

18. D (-4,-1)
E (0,-2)
F (-2,5)

Answer 4

Answer 5

geometry?

Answer 6

yep

Answer 7

what chapter?

Answer 8

chapter 9

Answer 9

okay :) give me a moment

Answer 10

ok

Answer 11

do you have graph or figure?

Answer 12

No I don't sorry

Answer 13

It's okay if you can't help.

Answer 14

(x,y) => (-y,x)
So rotation to 90 degree, switch the coordinates and then negate the ordinal (first one)
(-2,1) => (-1,-2)

Answer 15

same with 18

Answer 16

Oh okay thanks.

Answer 17

ur welcome
