Use the angle and the side values to calculate the bisector using the following formula: l = m = h = a s i n ( α) l = m = h = asin (\alpha) l = m = h = asin(α) Where: l = m = h. l = m = h l = m = h - in isosceles triangle bisector median and height are the same.
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.
