__Transformation:__

- The word”
“__transform____means__“.” In geometry, a transformation changes the position of a shape on a coordinate plane. That means a shape is moving from one place to another.__to change__ - The
of the object is called the__original shape__**pre-image**and theand position of the object is the__final shape__**image**under the transformation.

** Isometry :** Isometric transformation is a transformation that preserves

**congruence**. In other words, a transformation in which the image and pre-image have the same side lengths and angle measurements. The following transformations maintain their mathematical congruence Reflection (Flip) ,Translation (Slide), Rotation (Turn).
