1. Polyhedron 2. Face 3. Edge vs vertex

1. Polyhedron: A polyhedron is a three-dimensional figure with flat surfaces, also known as faces, that are polygons. The faces of a polyhedron intersect along edges, and the edges intersect at points called vertices.

2. Face: In a polyhedron, a face is a flat surface that is a polygon. The faces of a polyhedron can be triangles, rectangles, pentagons, or any other polygon.

3. Edge vs vertex: An edge is a line segment where two faces of a polyhedron intersect, while a vertex is a point where three or more edges of a polyhedron intersect. An edge connects two vertices, whereas a vertex is a specific point in space within the polyhedron.
