Polygonal Construction, Continued
You may use an alternate method of constructing triangles if triangles and
protractors are not available.
To draw an equilateral triangle using an alternate method of construction, use
Draw straight line AB the length of the base of your equilateral
Using the length of AB as a radius, strike an arc with A and with B
as a center.
These arcs will intersect at C.
Draw straight lines from A to C and B to C to complete the
Figure 2-39 illustrates the process for constructing an equilateral triangle
with an alternate method.
