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. WebMeasure the one angle of the triangle and the opposite side to that angle. 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.
