Radiant Reflections!
When reflecting an object on a coordinate plane it is easy to check if you have successfully carried out the transformation by using coordinate notation. When you do not have a coordinate plane you must look for the following to reveal if your reflection in correct, these attributes are also what make up a reflection. Look to see if your pre-image and images points are equidistant from the line of reflection. You must also look to see if the line of reflection is a perpendicular bisector to each corresponding set of points.
