In Fig. 162,let the cone and the plane Z be given, and let their line ofintersection be required. In drawing the figure, planes… … Fig. 162 to // were used as cutting planes. The E plane cuts fromZ the trace ZZ^, and from the cone it cuts the base abV. Thusa and 6 are determined by inspection as points on the line ofintersection. The plane A cuts from Z the line mn.
