This activity allows you to experiment with the transformation known as reflection.
A reflection over a line, k, is a transformation in which each point of the original figure has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line. i.e) it is a "flip" of the image.
Through an investigation involving three parts, you will learn some of the rules associated with reflecting points and figures over various (important) lines of reflection.
Begin by clicking on the box that says "Part 1." A triangle with vertices at A=(3,7), B=(2,4), and C=(10,5) will appear as well as a red line. This red line will be our line of reflection for our first set of trials and is known as y=0. Can you think of another name for this line?
