position draw theline gh 2^ long, parallel to XY,and the same distance from itas point e. Draw the projectorsgg and hJi till they meet a hori-zontal line drawn at the heightof point e. Then gh is the H.T., and gh the V.T. of the plane M. At the point m, where gh intersects the line L, draw… … 120. SOLID GEOMETRY Problem 91.
