None. Each face is an equilateral triangle.
None because a tetrahedron is a triangular based pyramid with 4 faces, 6 edges and 4 vertices
Four. The prefix "tetra" means four.
there are 24 right angles in all faces of a cube
A rectangular prism has six faces; each face has four right angles. There are 24 right angles in all.
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
A hexagon has only one face and this can have up to 5 right angles.
24.
A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
24
4
A cube has 6 faces, each having 4 right angles, for a total of 24 angles.
The right angles in a pentagonal prism happen where the long faces meet the pentagonal end-caps. Therefore, there are 10 right angles in the form.
