Question

What are the coordinates of A, if the given triangle is rotated counterclockwise 90 degrees around point C? A 4,-7 B-3,0 C-3,1

Answer 1

The correct answer is B (-3, 0).

Explanation:

To rotate the given triangle counterclockwise 90° around point C, I would suggest you get a piece of paper, and put it up to the screen. Trace that triangle and label the points. Rotating around point C, just means that wherever point C is, that point doesn't move. the other points do.
