Polygonal Construction, ContinuedSquaresYou may use triangles or protractors to construct squares. You may alsoconstruct a square using the circumscribed or inscribed method ofconstruction.To construct squares using the circumscribed method, use this table:Step123ActionDraw horizontal and vertical lines intersecting at right angles toeach other.Using the intersection of these lines as a center, draw a circle of adiameter that equals the distance from one corner of the square tothe 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 circlemethod.Figure 2-40.—Constructing a squareusing the circumscribedmethod.Continued on next page2-41
