Reflections • Every point is the same distance from a central line, and all shapes are the same size. • This is also called a FLIP. • The central line is also called the mirror line, because this is transformation is like a mirror reflection. • http: //www. mathsisfun. com/geometry/reflection. html Back to definitions
