The clockwise rotation of \(90^\) counterclockwise. Take note of the direction of the rotation, as it makes a huge impact on the position of the image after rotation. The angle of rotation should be specifically taken. Generally, the center point for rotation is considered \((0,0)\) unless another fixed point is stated. There are three basic transformations that can be done to a shape:1. The following basic rules are followed by any preimage when rotating: There are some basic rotation rules in geometry that need to be followed when rotating an image. In other words, the needle rotates around the clock about this point. In the clock, the point where the needle is fixed in the middle does not move at all. In all cases of rotation, there will be a center point that is not affected by the transformation. Examples of rotations include the minute needle of a clock, merry-go-round, and so on. Rotations are transformations where the object is rotated through some angles from a fixed point. So, we know that rotation is a movement of an object around a center.īut what about when dealing with any graphical point or any geometrical object? How are we supposed to rotate these objects and find their image? In this section, we will understand the concept of rotation in the form of transformation and take a look at how to rotate any image. ![]() We experience the change in days and nights due to this rotation motion of the earth. A rotation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. This section explained to you what rotations are and how to perform a rotation. We have distinguished between an object and its image. ![]() We have spoken about what reflections are and that we call the line of reflection also the mirror line. Whenever we think about rotations, we always imagine an object moving in a circular form. You have learned many important aspects of transformations already.
