Transformations Worksheets

What are Geometric Transformations? The geometric transformation includes taking a preimage and molding or transforming it to obtain an image. Broadly, there are two types of geometric transformations: The non-rigid transformation that alters the size of the preimage while keeping the shape intact. The rigid transformation doesn't alter the size or shape of the preimage. Types of Transformation - Rigid and non-rigid transformations are further divided into different categories. Rotation, translation, and reflection fall in the rigid transformation, and dilation fall in the non-rigid category. Below we have briefly discussed each sub-category. Translation - It is a type of transformation that slides or moves across the plane or through space. In translation, all points of a figure move or slide in the same direction and cover the same distance. Rotation - As the name implies, rotation moves the figure about a line or point. It basically means to spin or turn the figure at a point. The point of turning or spinning is known as the center of rotation. This center can lie outside the figure or be present on the figure. Reflection - Reflection is a transformation that involves flipping the shape across the line to create a mirror image, in the mirror image, the measures of lines and angles are preserved. Dilation - Dilation is the transformation that involves expanding or contracting the shape without disturbing its orientation or shape.
