Take K two to leftof X, and G two to left of K bisect GK in H j draw GR, HSand KT at right angles to B.L., and b in length join RST.Take TP 3, and with centre T and distance TP describe arcPN, cutting HS in N : join KT and KR : KRT will be theplan of the triangle. Via N draw UNQ parallel to RT, cutting GR in Uand KT in Q with centre K and distance KQ describe arcQL, cutting B.L. in L and with same centre and distanceKT describe arc TY, cutting B.L. in Y. Join G C.Y.,H C.Y. and K C.Y. and join also LM and Y]I to cutK C.Y. in E and C. Via E draw EAF, and throughC draw CDB, every single parallel to B.L., and cutting H C.Y. in Aand D respectively join BA and AC : then ABC will be thetriangle required. For CK = KY = KT = 5, and EC = LA =QT = NS = height of triangle, and EK = KL==KQ. HenceAD = NS and AH = HN. But because triangle is isosceles, GHis produced equal to HK hence BD = DC = GH = HK, then CA= NT = NR = BA. (Fig. 23.)<\/i><\/p>\n
