Fig. 2 shows the elevation of a right cone C and a sphere S in contact with each other. Also shown is the position of a point P on the front of the cone.
(a) Draw the elevation and plan of the solids in contact.
(b) Show the projections of another right cone standing on the horizontal plane so that it is in contact with the base of the cone C at the point P and touches the sphere S at a point 20 mm above the horizontal plane.
(c) Draw the traces of a tangent plane to the cone C and the sphere S.
