## DIRECTIONS:

In the GeoGebra applet below,
1) Select the REGULAR POLYGON tool. Then plot 2 points

*A*and*B*. In the pop-up box that appears, enter "3" (without the " "). This creates an "regular triangle" (equilateral & equiangular triangle). 2) Now use this same tool to construct a regular quadrilateral (square) and regular octagon. 3) Select the MOVE tool. Move any one (or more) of the**blue points**around. Note these polygons always remain regular. When you're done (or if you're unsure of something), feel free to check by watching the quick silent screencast below the applet.
