This section cover's Euler's theorem on planar graphs and its applications. After defining faces, we state Euler's Theorem by induction, and gave several applications of the theorem itself: more proofs that \(K_{3,3}\) and \(K_5\) aren't planar, that footballs have five pentagons, and a proof that our video game designers couldn't have … merrell shoes moab 3
