Reflection over the line y=x - Rigid Motion

Reflection over the line y=x is a lesson that will show you the properties that occur when a reflection occurs over the line y=x. A rigid motion is a transformation that does not change the shape of the object. Does this occur when we reflect over the line y=x? At the end of the lesson you should be able to answer this.
