: The following coordinate plane shows the 180( rotation around the origin of (EFG to form (EFG. Function Notation: R180(Rotating with graph paper AND Rotating without graph paper: The steps are the same: 1) Determine which quadrant the rotated image will move to. 90 degrees moves 1 quadrant. 180 degrees moves 2 quadrants. 270 degrees moves 3 ... rotation is clockwise, the angle is negative. If the rotation ends at exactly a quarter rotation, producing initial and terminal sides which are perpendicular, the angle is said to be a right angle (θ = 90 degrees), as shown below. If the rotation is less than a quarter, the angle is said to be acute. If the rotation is greater than a quarter
May 27, 2020 · For now, you will specifically be looking at 90°, 180°, and 270° rotations around the origin. Unless otherwise specified, a positive rotation is counterclockwise, and a negative rotation is clockwise. Use the interactive below to explore how 90°, 180°, and 270° rotations are related to the x coordinates and y coordinates of a point.
