Webso looking at the picture in the video, you should be able to see that it is < 90 counterclockwise (between 0 to 90) and which would be >270 clockwise (between - 270 and - 360 degrees). While it may not always give the … Web90 DEGREE CLOCKWISE ROTATION When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Example 1 : Let K (-4, -4), L … WebWhen you rotate by 90 degrees, you take your original X and Y, swap them, and make Y negative. So from 0 degrees you take (x, y), swap them, and make y negative (-y, x) and then you have made a 90 degree rotation. What if we rotate another 90 degrees? Same thing. Our point is at (-1, 2) so when we rotate it 90 degrees, it will be at (-2, -1) randall thomas wooster ar
