Question from Jeramie: When we have a regular tetrahedron, is it always true that all the angles of the triangles measure 60 degrees? |
Hi Jeramie,
If the tetrahedron is regular then each of the triangular faces is regular which implies that the triangular faces are equilateral. Hence each of the internal angles of the triangular faces measure 60 degrees,
