oughc and m is therequired vertical trace. Examples.—1. Draw the plan and elevation of a cone with itsbase on the ground, diameter of base if, height 2^. Drawthe traces of a plane which touches the cone along a generatorwhose plan makes 450 with xy. 2. Draw the plan and elevation of a line inclined… … 344 PRACTICAL SOLID GEOMETRY chap. 287. Problem.—A given cone, vertex V, rests with itsbase on the horizontal plane, determine the traces of aplane which shall pass through a given external point Pand be tangential to the cone. The required plane must contain the line VP. Thereforeobtain h, the…
