### Area and Perimeter of Regular Polygons

*Construction of a Square*

1.) Begin with an arbitrary line segment.

2.) Construct two lines perpendicular to this
segment which go through each of the endpoints.

3.) Construct a circle which has its center
as one of the endpoints of the original segment and its radius
length as the length of the segment. Mark the point where the
circle intersects one of the perpendicular lines.

4.) Construct a line parallel to the original
segment which passes through the intersection point found in the
previous step.

5.) Construct segments as sides of square.
