Question

Point A' is the image of point A under a rotation about the origin (0,0) 2 Determine the angle of rotation 0 270 degrees clockwise 180 degrees O 90 degrees counterclockwise o 90 degrees clockwise 0 270 degrees counterclockwise

Answer 1

90 degrees clockwise, 270 degrees counterclockwise

Explanation:

I did it on Kahn academy and it said it was right.

Answer 2

180 degrees rotation

Firstly, we need to identify the coordinates of both points, so as to be able to determine the rotation relationship

From what we have;

A is (3,-4) while A' is (-3,4)

So, the rotation relationship needed is the one that turns (x,y) to (-x,-y)

This kind of rotation relationship is 180 degrees clockwise or counter-clockwise rotation

In essence, we simply select 180 degrees rotation as the correct answer choice
