No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.

None because a tetrahedron is a triangular based pyramid which has 4 faces, 6 edges and 4 vertices.

It has twelve angles but all of them need not be acute.
