Can you draw a shape without lifting your pen and retracing any edge? In this video, we explore Eulerian paths from graph theory using two example shapes — one possible, one impossible. Learn the exact conditions that make such a path possible, see a step-by-step proof for the first shape, and understand why the second shape fails.
