Composition of transformations

This is a composition of a transformation. A composition of a transformation is two or more transformations preformed on one pre-image. In my composition I first translated my pre-image ABC one up and two to the right. Second I reflected my translated image A'B'C' over the x-axis. Finally I rotated each point in polygon A''B''C'' 90 degrees counterclockwise. This composition can be written as T<1,2>Rx-axisR90.
