A transformation is an operation that maps a figure. The new figure is the image and the original figure is the preimage.
A function is a correspondence between sets of points so that each point in the first set corresponds to exactly one point of the second set. In algebra, a mapping is called a range.
An Isometry is a rigid transformation that maps every figure onto a congruent figure so that the shape and length are congruent figures. A transformation in the plane is an isometry if it preserves relative distance angle measures.
What is a transformation?
In mathematics, we can refer to the word transformation as that which causes a shape to be converted into another similar shape.
We have three types of rigid transformations in the field of mathematics. These are called, translations, rotations and reflections. The non rigid transformations are those types of transformations that do not have to preserve the angles and the length measurements.
