Incenter of tetrahedron
WebA regular tetrahedron is divided into four congruent pieces, each of which is bordered by three large and three small quadrilaterals. The quadrilaterals are kites, which have two pairs of adjacent sides of the same length. Each piece is a distorted cube.

WebIn the case of a regular tetrahedron, then yes. In general, no. Consider the case of a tetrahedron with an equilateral base, points on the unit circle. Let the fourth point of the tetrahedron be directly above the centre of the circle. The inradius of the base is 1/2. Therefore, the strict upper limit of the radius of an inscribed sphere is 1/2. dust heapWebThe the tetrahedron's incenter O is given by: O = a A A + b A B + c A C + d A D, where A = a + b + c + d is the tetrahedron's surface area.
