Polygonal Construction, Continued
Drawing geometric figures around a circle is known as the inscribed method
of polygonal construction.
The circle is inside the figure and the sides of the
geometric figure are tangential to the circle circumference. The diameter of
the circle is measured at a 45° angle to the horizontal. Measurements for
figure construction is made from the diameter or across the flats.
Figure 2-33 shows the construction of a square using the inscribed method.
