Webwill be defined to be the sphere containing the vertices of Δ. Let R (Δ) denote the radius of the circumscribed sphere. As previously noted, the circumscribed sphere is not necessarily the boundary of the smallest ball containing Δ, hence R(Δ) and R (Δ) are not necessarily equal. Conjecture 4. If x ∈ Δ, then R (Δ) ≤ max v∈V R (Δx ...

WebEvery tetrahedron has a circumscribed sphere passing through its four vertices and an inscribed sphere tangent to each of its four faces. A tetrahedron is said to be circumscriptible if there is a sphere tangent to each of its six edges (see [1, §§786–794]). We call this the edge-tangent sphere of the tetrahedron. Let P denote a tetrahedron ... Web3D model of regular tetrahedron.

We prove that the radius of the edge-tangent sphere is at least 3 times the radius of its inscribed sphere. This settles affirmatively a problem posed by Z. C. Lin and H. F.
