ugh C and G.Fold BM perpendicular to CG.Take MP, CN, and NL each = BM.Fold PH, NK, LF at right angles to CG, as inFig. 26. IN PAPER FOLDING 29 Take NK=BM, and fold KE at right angles toNK. Then the pieces 1, 4, and 6, 3 and 5, and 2 and 7form three equal squares. Now CG2 = 3BG2,and from the… … Fig. 27. Then AB-AX=XB1, and AM=MX.Take BN=AM or MX.Then MJV=XB. Lay off NP and J/i? equal to MN, so that i3 andR may lie on j5C and AD respectively. PAPER FOLDING 31 Lay off RQ and PQ = MR and NP. MNPQR is the pentagon required. In Fig. 19, p. 22, AN, which is equal to AB, hasthe point N on the…
