Transformations

Reflections and Translations

What is a Translation

A rigid motion transformation that moves every point of one figure the same amount and preserves the orientation. 

What is a Reflection

A type of transformation where every point is mapped across a line. The original point and the new point are equidistant from the line. 

What is a Reflection Line?

a line that acts as a mirror so that corresponding points are the same distance from the mirror
