Euler's Polyhedral Formula

Euler's Polyhedral Formula is a fundamental rule in geometry that relates the number of faces, vertices, and edges of a simple, convex polyhedron (a 3D shape with flat surfaces). It states that: **Number of faces + number of vertices = number of edges + 2.** In simple terms, if you count all the faces and corners, and then compare that to the edges, there's always a consistent relationship. This formula helps mathematicians understand and classify different shapes and ensures their geometric consistency.
