90 DRAWING. Here CA = AB = AD = AE = 4, EF = FM = 2, CtF=11hence K is centre at intersection of diagonals and HK = GF.(Fig. 53.) Note.—The sphere ^vill not touch the P.P. unless HK =KF. Example S.—Draw a cube, edge 4, touching P.P. 4 toright, and in this place a sphere whose radius = 2. Here… … Fig. 54. Draw cube, and diagonals of those sides, perpendicular toP.P., join intersections, and bisect this horizontal line assho^\^l. 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, scale \ = 1.) 1.…
