t A and B, intersecting at pointc, be the given lines. Find the traces of A and B (Prob. 1,§ 37). The required trace HQ is determined by the twoiZ-traces sx and s2; the trace VQ by the two P-traces tx and L. Check. The H- and F-traces of a plane must intersect onthe ground line (§ 46). Hence IIQ… … Fig. 135. In Fig. 136 the IZ-trace of the given line B is too far removedto be used in the construction. The plane Q, containing A and
