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.
rectangular prism all angles are acute angles yes or no? * * * * * No, none of the angles are acute. They are all right angles because each face is a rectangle and each angle in a rectangle is a right angle.

A triangle if it is a triangular based pyramid
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.

4 on each face.

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