an example of this class. From0 corners A, B, and E can be seen,- and from P the corners G and D. 411 theangles around the points 0 and P are measured as well as the distances OA,OB, OP, 0E,: PC,, and PD. The lengths PS and Pill can be computed from the tri-angles BOP and HiOP,. respectively. The… … Fig. 6. Fig. 9. A field of this form is shown in fig. 8. fhe point 0 is chosen so that Aand D are visible, and J? is taken so that B, C, ffi, and F can oe seen. Flagpoles are placed at suitable points in the boundary lines, such as E and f,and the four angles around 0 and the four radial distances…
