Rotation or rotational motion is the circular movement of an object around a central line, known as axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation.
A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. For example, this animation shows a rotation of pentagon I D E A L about the point ( 0 , − 1 ) .
- It’s because you’re rotating in the order of the coordinate plane’s quadrants, which goes from right to left to down to right (**counterclockwise**)
- Great question! There are actually several helpful shortcuts for finding rotations. For rotating 90 degrees counterclockwise about the origin, a po...
- You could rotate each point of the polygon *on its own*, and then connect each point correctly. Remember that each point will be the same distance...
- @garrettcummings22, I realize the frustration of these geometric principles, but these same principles are the foundations of graphic design, sever...

- The rotation is a type of transformation in Maths is the circular motion of an object around a centre or an axis or a fixed point.
- In real-life, we know the earth rotates on its own axis, which is an example of rotation. A group of people holding their hands and forming a circ...
- The rotation could be clockwise or counterclockwise. If there is an object which is to be rotated, it can be done by following different ways: 90...
- The point about which the object is rotated is the point of rotation. The amount of rotation measured in degrees is called the angle of rotation.
