Which of the following would be a line of reflection that would map ABCD onto itself? Square ABCD with A at negative 3 comma 0, B at negative 3 comma 2, C at negative 1 comma 2, and D at negative 1 comma 0.

y = 2
3x + y = 1
3x + y = −1
−3x + 3y = 9

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

i think the answer is b

it should be a.

hope it
