Construction of Inscribed and Circumscribed Spheres of a Regular Tetrahedron

This GeoGebra example demonstrates the geometric construction of the inscribed and circumscribed spheres of a regular tetrahedron. By constructing the four vertices, six edges, and four faces of a regular tetrahedron, it determines the geometric center and calculates the perpendicular distance from the center to each face (inscribed sphere radius) as well as the distance from the center to each ve
