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. ![]() 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. Below are several geometric figures that have rotational symmetry. Rotations are transformations where the object is rotated through some angles from a fixed point. A geometric figure or shape has rotational symmetry about a fixed point if it can be rotated back onto itself by an angle of rotation of 180° or less. 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. Whenever we think about rotations, we always imagine an object moving in a circular form. ![]()
