trace of the required plane,parallel to ^iV. VjS will be parallel to A\ 72. Case 2. To pass a plane through a givenpoint perpendicular to a given line. Principle. Since the required plane is tobe perpendicular to the given line, the traces ofthe plane will be perpendicular to the projec-tions of… … Fig. I 16. Method. 1. Through the given point passa line parallel to one of the coordinate planesand lying in the required plane. 2. Deter-mine the trace of this line, thus determiningone point in the required trace of the plane.3. Draw the traces j)erpendicular to the pro-jections of the given…
