Videos, worksheets, games and acivities to help Geometry students learn about transformations on the coordinate plane. In this lesson, we will look at composition of transformation..

Composition of Transformations
A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines). A composition of reflections over intersecting lines is the same as a rotation (twice the measure of the angle formed by the lines).

Glide Reflection
A glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over.
A common example of glide reflections is footsteps in the sand.
