You will learn about reflecting a shape in this applet.
Click on the reflect across a line on the tool bar, and then click the y-axis and the triangle that is provided. Observe what happens, and note the coordinates. How do these coordinates compare to the original? Now make a line across the x-axis and repeat. Try a variety of shapes and points, and make note of your observations.
