forming a solid rightangle at h. Let the line a b be inclined atsome given angle 6 to the j^lane of projection.Locate a vertical plane parallel to a h and pro-ject the latter upon it at ab, at ^° to thehorizontal. Since the ])lane of the other twoaxes is perpendicular to ah, ab, its traceswill be… … centre b, obtaining c. Cj and draw arc c^c. Join a with c; then a c is the trace of the plane of the axes h a and b c, and being perpen-dicular tu the third axis we may di-aw the latter as the line ebd, making 90° with a c. 242 THEORETICAL AND PRACTICAL GRAPHICS.
