WebRotation means the circular movement of somebody around a given centre. It is possible to rotate many shapes by the angle around the centre point. In three-dimensional shapes, … WebBefore Rotation. (x, y) After Rotation. (-y, x) When we rotate a figure of 270 degree clockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Problem 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. If this triangle is rotated 270° clockwise, find the ...
