Fig. 143. Construction (Fig. 143). Let it be required to pass the planethrough the line A. Assume any point con J; through c drawthe line D parallel to B. Pass the required plane Q throughthe lines A and D (Prob. 6, § 106). … Fig. 144. X, § 107] PARALLEL LINES AND PLANES 85 Special Case I. Suppose the second line is parallel to IIor V; then no auxiliary line is needed. Thus, in Fig. 144, letus find the plane which contains the line A and is parallel toB. The .ff-trace of any plane which is parallel to B must beparallel…
