Polygonal Construction, ContinuedTrianglesYou may use an alternate method of constructing triangles if triangles and(Continued)protractors are not available.To draw an equilateral triangle using an alternate method of construction, usethis table:StepAction1Draw straight line AB the length of the base of your equilateraltriangle.2Using the length of AB as a radius, strike an arc with A and with Bas a center.34These arcs will intersect at C.Draw straight lines from A to C and B to C to complete thetriangle.Figure 2-39 illustrates the process for constructing an equilateral trianglewith an alternate method.Figure 2-39.—Using a compass toconstruct an equalateral triangle.Continued on next page2-40
