### Area and Perimeter of Regular Polygons

*Construction of a Regular Triangle*

1.) Begin with an arbitrary line segment.

2.) Construct two circles, both having a radius
length equal to the length of the segment. One circle's center
should be one of the endpoints of the segment, and the other circle's
center should be the other endpoint. Mark the intersection of
the circles.

3.) Construct segments from each of the endpoints
of the original segment to the intersection point marked above.

4.) Hide path objects.
