ANGLE DOUBLING

A triangle picture is shown along with text information about a triangle (the information does not match the picture). Grab triangle vertices and move them with the mouse to make the angles in the picture match the text.

For example, if the vertices are named X, N and L, then XNL=21 means that you need to make the angle at vertex N 21 degrees by moving the other vertices. A big happy face indicates the correct answer!

This is one program from a CD of over 200 math programs for middle school students by Gary Smith - visit his web site for more information.
