Edge
Tetrahedron in geogmetry is composed of four triangular faces, three of which meet at each vertex.
Triangular prisms have two triangular bases (parallel to each other) that are connect by three rectangles. Therefore, it has 5 faces (the flat shapes described earlier), 6 vertices (the corners where more than 2 faces meet), and 9 edges (the segments where only two faces meet).
edge
12 4 edges on each end (8 total) where the rectangle side faces meet the square end faces and 4 edges the rectangular faces meet each other.
Spheres, cones and cylinders have no perpendicular faces that meet each other at right angles.

The fixed point at the intersection of all the faces of the pyramid is called the VERTEX of the pyramid.
When two objects meet and share the same space while overlapping with each other, it is called intersection.

A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
edge
A tetrahedron is made up of 4 triangular faces, 3 of which meet at each corner or vertex. This is sometimes called a pyramid.
