Question

What is the image of C for a 90 degree counterclockwise rotation about A?

Answer 1

Option A. (7, 3)

Explanation:

When C is rotated 90° counterclockwise about the point A then C' will come parallel to the point A.

Now we can find the coordinates of the image of point C.

Distance between point A and C is 4 units, so x coordinates of C' (image) will be = 3 + 4 = 7

And y coordinates will remain as 3.

So the new image point C' will be (7, 3)

Option A. (7, 3) is the correct option.

Answer 2

counter clockwise would be rotating it up to the right.

C is 4 spaces away from A ,

A is on X3 & Y3 so 4 +3 = 7

so it would be x7 & Y3 so (7,3), the first answer
