Squares
You may use triangles or protractors to construct squares. You may also
construct a square using the circumscribed or inscribed method of
construction.
To construct squares using the circumscribed method, use this table:
Step

Action
Draw horizontal and vertical lines intersecting at right angles to
each other.
Using the intersection of these lines as a center, draw a circle of a
diameter that equals the distance from one corner of the square to
the opposing corner.
Where the circle intersects the horizontal and vertical centerlines,
use a 45° triangle to draw connecting lines to form the square.
Figure 2-40 shows a square constructed using the circumscribed circle
method.
