    1. I suppose you have to bisect the opposite edge from each corners. The intersection of all the bisecting lines will give the apex.

    1. As you know , a regular tetrahedran is made of 4 equilateral triangles... to define axis " the perpendicular line drawn fron the apex to the opposite face ". Since the triangles are equilateral , i suppose the length of the axis is same everywhere.. so no longer or shorter axis in this case.
