We can also name points and graph them. Above we defined a triangle by first defining three points, then the three segments that join them. Here we will use a little more sophisticated block of commands to do all of that, plus graph the triangle and automatically adjust the size of the graph to fit the triangle. A, B, C in the same order you specified them. Lets use the command see what this new version does.
Triangles are polygons of three sides.
We can use Maple's built - in capabilities to display more general polygons.
