of a plane which shall touchthe cone of Ex. 1, page 354, and pass through a point P, 1 tothe right of the vertex, 2 in front of the vertical plane, and 1above the ground. 2. The axis VA of a cone, vertical angle 250, coincides with xy. Apoint P is 1 \ distant from both planes of projection, and… … 362 PRACTICAL SOLID GEOMETRY chap. 297.
