WebFor the two centers to coincide, their coordinates need to be proportional which, in this case, requires the tetrahedron to be equiareal, i.e., to have all faces of the same area. But it's known that equiareal tetrahedra are also isosceles. WebA regular tetrahedron is a 3-dimensional geometric solid.It is also a special type of pyramid.It consists of a base that is a triangle and a point directly over the incenter of the base, called the vertex.The edges of the tetrahedron are the sides of the triangular base together with line segments which join the vertex of the tetrahedron to each vertex of the …

WebFrom these face area values we can then calculate the incenter of the tetrahedron, and thus also the center of the largest inscribed sphere, using the weighting formula O = (a/t)A + (b/t)B + (c/t)C + (d/t)D where O is the co-ordinate triple of the incenter; A, B, C and D are the co-ordinate triples of the vertices;
