90 DRAWING. Here CA = AB = AD = AE = 4^ EF = FM = 2, Gr=llhence K is centre at intersection of diagonals and HK = GF.(Fig. 53.) !NoTK—The sphere will not touch the P.P. unless HK =KF. Example S,—Draw a cube, edge 4, touching P.P. 4 to right, and in this place a sphere whose radius =sphere will… … Fig. 54. Draw cube, and diagonals of those sides, perpendicular toP.P., join intersections, and bisect this horizontal line asshown. The circle drawn on this line as diameter will repre-sent the sphere, and touch the centre of each side. (Fig. 54.) Exercise XIY. (H = 6, L.D. = 4, scalei = l.) 1.…
