The simple formula for the X and the Y coordinate is as follows: For the x-axis graph rotation, we have the formula: Xxcos()+ysin() For the Y-axis graph rotation, and transformed co. We can move the object in the clockwise and in the anticlockwise directions. The vertices of the quadrilateral are first rotated at 90 degrees clockwise and then they are rotated at 90 degrees anti-clockwise, so they will retain their original coordinates and the final form will same as given A= $(-1,9)$, B $= (-3,7)$ and C = $(-4,7)$ and D = $(-6,8)$. We can rotate the angle () by rotating a point around the x-axis. If a point is given in a coordinate system, then it can be rotated along the origin of the arc between the point and origin, making an angle of $90^$ rotation will be a) $(1,-6)$ b) $(-6, 7)$ c) $(3,2)$ d) $(-8,-3)$. Hence, the transformation matrix is 2 6 3 1 Solved Example: 2 A triangle is defined by 2 4 4 2 2 4 Find the transformed coordinates after the following transformations. Let us first study what is 90-degree rotation rule in terms of geometrical terms. On solving these equations we get, a 2, b 3, c 6 and d 1. If we are required to rotate at a negative angle, then the rotation will be in a clockwise direction. The coordinates stay in their original position of x and y, but each number needs to be multiplied. So, all points should be in the third quadrant. ![]() Later, we will discuss the rotation of 90, 180 and 270 degrees, but all those rotations were positive angles and their direction was anti-clockwise. The rule of a 180-degree clockwise rotation is (x, y) becomes (-x, -y). If I rotate 270 degrees, the shape will be in the third quadrant. The -90 degree rotation is a rule that states that if a point or figure is rotated at 90 degrees in a clockwise direction, then we call it “-90” degrees rotation. ![]() You can find both the Clockwise and AntiClockwise directions of rotation by the rotation calculator. Clockwise and AntiClockwise Rotation Rules: We need to understand that the rotation can be done in both Clockwise and AntiClockwise directions. ![]() Read more Prime Polynomial: Detailed Explanation and Examples Rotation is a movement around an axis and by rotation geometry we define that.
