Fig. 89 represents a condition when allfour traces of the^ given planes intersect GLin the same point, neither plane containingGL. This point of intersection of the traces,5, is one point in the required line of inter-section between the planes (Case 1). Asecond point, a, is obtained by passing theauxiliary cutting plane X parallel to JT, inter-secting plane N in line Q and plane S in lineB. Point a, the point of intersection of theselines, is a second point in the req
