A triangular pyramid is a pyramid with a triangular base. A tetrahedron is a triangular pyramid with congruent equilateral triangles for each of its faces
For a tetrahedron, the angle between and edge and a face is arctan( square root of 2)
the angle between two faces is 2(arctan(square root 2)) Angle between the segments joining the center and the vertices is arccos (-1/3)
Other triangular pyramids have different angles which will depend on weather it is regular or not, and the details of the sides lengths.

If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.
None normally
