الوصف: | Proposition 5 of Book I of Euclid’s Elements, better known as the Pons Asinorum or the Asses’ Bridge, and its converse, Proposition 6, state that two sides of a triangle are equal if and only if the opposite angles are equal. A generalization of this statement to higher dimensional d-simplices is considered in [14], where it is shown that such a generalization holds only if the underlying d-simplex is orthocentric. In this paper, it is shown that a reasonably satisfactory generalization holds for all, not necessarily orthocentric, tetrahedra. It is also shown that a stronger statement than that given in [14] holds for orthocentric tetrahedra. |
