Abstract:
We obtain formulas for the volume of a spherical tetrahedron with $\mathbb Z_2$-symmetry realized as rotation about the axis passing through the midpoints of a pair of skew edges. We show the dependence of the volume formula on the edge lengths and dihedral angles of the tetrahedron. Several different formulas result whose scopes are determined by the geometric characteristics of the tetrahedron.
Keywords:
tetrahedron, spherical space, volume, Gram matrix.
