For a tetrahedron, suppose that all internal angles of faces and all dihedral angles are less than a fixed constantCthat is smaller thanπ. Then, it is said to satisfy the maximum angle condition with the constantC. The maximum angle condition is important in the error analysis of Lagrange interpolation on tetrahedrons. This condition ensures that we can obtain an error estimation, even on certain kinds of anisotropic tetrahedrons. In this paper, using two quantities that represent the geometry of tetrahedrons, we present an equivalent geometric condition to the maximum angle condition for tetrahedrons.
