![]() ![]() The algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x). Therefore, the algebraic rule for a figure that is rotated 270° clockwise about the origin is (y, -x) Therefore, the coordinate of a point (3, -6) after rotating 90° anticlockwise and 270° clockwise is (-6, -3). For a 180 counterclockwise rotation, the rule for changing each point is. For a 90 counterclockwise rotation, the rule for changing each point is. Notice how the points change and record your findings below. A simple TRANSFORMATIONS tutorial to show how to carry out accurate rotations. Draw a line segment MN joining the point M (-2, 3) and N (1, 4) on the. Now rotate PQ through 180° about the origin O in anticlockwise direction, the new position of points P and Q is: Thus, the new position of line segment PQ is PQ. Rotating 270° clockwise, (x, y) becomes (y, -x) Use the slider to focus on 90, 180, and 270counter-clockwise rotations. Solution: On plotting the points P (-3, 1) and Q (2, 3) on the graph paper to get the line segment PQ. Rotating 90° anticlockwise, (x, y) becomes (-y, x) Given, the coordinate of a point is (3, -6) What will be the coordinate of a point having coordinates (3,-6) after rotations as 90° anti-clockwise and 270° clockwise? Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees counterclockwise. so 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).Examples What rotation will take P to P’ 1. Before Rotation (x, y) After Rotation (y, -x) When we rotate a figure of 270 degree counterclockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. When we rotate clockwise or counterclockwise, the two rotations should always add up to degrees. The rule given below can be used to do a counterclockwise rotation of 270 degree. The amount of rotation is called the angle of rotation and it is measured in degrees. Clockwise (CW): Counterclockwise (CCW): There are degrees in a circle. The fixed point is called the center of rotation. What is the algebraic rule for a figure that is rotated 270° clockwise about the origin?Ī rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point. ![]()
