The only pyramid with a square base that has equilateral faces, is one where the diagonal of the base is exactly twice as long as the pyramid is high.
A triangle if it is a triangular based pyramid
A lot of things. For example, a cube has 8 vertices, the square pyramid has 5. A cube also has more edges and faces than the pyramid. All the faces of the cube are squares, while the pyramid only has one square face. Also, all the angles in the cube are right angles, while the angles in a square pyramid (in the usual sense of a pyramid where the apex is directly above the center of the base) are acute. In any case, they are not all right angles.
A triangular pyramid is a pyramid that has 4 faces where each face is a triangle. Just type it in on www.google.com/images
None!!!! Every face is angles to its adjacent and opposite faces.
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.

a pyramid where each face is the shape of a triangle
Just the one and it is the base face
a triangle
Square-based pyramid.
The height of each lateral face of an unspecified object is unknowable.

A tetrahedron is an example of a triangular pyramid. Every face is a triangle, and each face touches every other face on one edge.
