Extend the xy-plane shown below then graph the rotated image of \Delta ABC. The rule for a rotation by 90 about the origin is (x,y)(y,x) . This also means that when a figure is rotated in the same direction on a Cartesian plane, all the points will exhibit the same behavior. It should be . The last parameter is the angle, in degrees. Then the x- and y-coordinates of the new point have the same absolute value and simply the opposite plus and minus signs. The following diagram, we will explore the rotation rules: as you can better understand each. In step 1, we have to apply the rule of 90 Degree Clockwise Rotation about the Origin (x, y) (-y, x) Next, find the new position of the points of the rotated figure by using the rule in step 1. Direct link to Jonathan Huang's post Why did they put a 170 de, Posted a month ago. The figure or the point is rotated about a fixed point called the center of rotation. Since the rotation is 90 degrees, you will rotating the point in a clockwise direction.

Counterclockwise rotations are denoted by positive numbers. If the figure being rotated is outside a Cartesian plane, use the first method to accurately graph the projected image. To perform the 90-degree counterclockwise rotation, imagine rotating the entire quadrant one-quarter turn in a counterclockwise direction. Any help appreciated. Yes there is a better way to do it. Have thoughts? Once we have found the center of rotation, we have several options for determining the angle of the rotation. To solve a math equation, you need to decide what operation to perform on each side of the equation. Since the rotation is 90 degrees, you will rotating the point in a clockwise direction. Identify the transformation from ABC to A'B'C'. counterclockwise, find the vertices of the rotated figure and graph. In other words, switch x and y and make y negative. The most common rotation angles are 90 degrees, 180 degrees, and 270 degrees. Rotations preserve distance, so the center of rotation must be equidistant from point. By observing the effect of the rotation on each of the resulting images of the four points, we can see that the first three rotations exhibit what we expect from a 90 degree clockwise rotation: (x, y) \rightarrow (y, -x). If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b).
