Understand how to graph reflections on the coordinate plane Learning goal Understand how to graph reflections on the coordinate plane
vocabulary Reflection – a transformation in which a figure is flipped over a line. Line of reflection – the line over which a figure is reflected. Line symmetry – occurs when a figure can be folded so one side is the mirror image of the other side.
In a reflection each point and its image are the same distance from the line of reflection so the pre-image and the image are congruent. Page 462
