Question

What is the image of C for a 180° counterclockwise rotation about P?
A. (3, 5)
B. (3, -3)
C. (3, 0)
D. (3, 3)

Answer 1

Alright. The question asks a 180 degree rotation counterclockwise. But does the direction of rotation matter when its 180 degree? Just measure the distance of C from P, turn it around, and find the new location of C. Try it out.

Answer 2

no it doesn't

Answer 3

@ehmuleeee : Correct! Now, you know the distance of C from P. Just turn C around now. You do this by simple moving UP from P the same distance that was the distance of C from P!

Answer 4

okkkk

Answer 5

Did you get the answer?

Answer 6

still sorta confused lol

Answer 7

No problem. The simplest way to find the answer is this: Both A and C are equidistant from P. So just find the co-ordinates of A! That is your answer!

Answer 8

(3,3)?

Answer 9
