idered as the arc of a circle passing through B, C, and B. Tiiere-fore, BAG is the projection required. Queries.—Will a solution of this problem be possible for all values of J andc ? How does it appear from the projection ? EXAMPLES. 1. Having given h = 110°, and c = 60°, toproject the triangle.… … 101.
