Fig. it. The angle a° is the complement of the angle the fine AB makes with the H.P.Therefore a° is the inclination of the given plane RST to the H.P.; and, for similarreasons, the angle 0° is the inclination of the plane RST to the V.P EXERCISE VI. Find the inclinations to the planes of… … N.B.—Take each of the planes A, B and C as a separate problem and work to a large scale. TRACES OF LINES 17 TRACES OF LINES Sections. A line AB is represented by its projections at (i) in Fig. 12. Itwill be observed that the A end of it is a i)oint in the V.P. at a\ and that the B endof it is a…
