what is the meaning of these words!
Polyhedron
Face
Edge vs vertex
- Polyhedron: A polyhedron is a three-dimensional shape with flat faces, straight edges, and sharp corners or vertices. Examples of polyhedrons include cubes, pyramids, and prisms.
- Face: In a polyhedron, a face is one of the flat surfaces that make up the shape. Faces are defined by straight lines and connect at edges forming the vertices of the polyhedron.
- Edge vs vertex: An edge is where two faces of a polyhedron meet, creating a line segment that connects two vertices. A vertex, on the other hand, is a corner where three or more edges meet. Vertices are the points of the polyhedron where the faces intersect.
