A comprehensive analysis of the Snellius-Pothenot problem

Evgenii Nikitenko, Yurii Nikonorov, Michael Rieck

It is known that a point in three-dimensional Euclidean space whose coordinates are equal to the cosines of the angles $∠ B D C, ∠ A D C, ∠ A D B$ , where the point $D$ lie…

On face angles of tetrahedra with a given base

E. V. Nikitenko, Yu. G. Nikonorov

Let us consider the set $I^c ◯ (△ A B C)$ of all tetrahedra $A B C D$ with a given non-degenerate base $A B C$ in $E^{3}$ and $D$ lying outside the plane $A B C$ . Let us denote b…
