Let AABC be the spherical triangle shown in Figure 4.3. Perform the construction in the proof of Theorem 4.1.2 on the sphere, starting with this triangle. Convince yourself that the point F constructed is in the interior of LACD if and only if u(LBAC) < 90°. Draw diagrams illustrating both possibilities.
