Variable-Geometry Trusses: What's Your Angle?
Dianne P. O'Leary
Program to draw Figure 25.1:
drawtrussfig.m
Note: The formula in Challenge 25.1 depends on the choice of orientation. When the triangles with 2 points on the base and one on the top are flat in the base plane, the top is assumed to point to the right, not the left. If you make a different choice, then your signs may be different.
