All triangle proofs
Web32. There is always the "taxicab" proof. Start at a vertex and take a cab trip around the triangle. The cab will have turned through an angle of 360 o Extend the sides of the triangle appropriately and you will get three 180 o angles with the vertex angles being supplementary to the turns taken by the cab. WebJul 22, 2015 · Let Gs,t denote the wind-wheel graph on n vertices obtained by appending s triangle(s) to a pendant vertex of a path Pt+1 with just a vertex in common. In this paper, we prove that all wind-wheel graphs are determined by their Laplacian spectra as well as signless Laplacian spectra. As Gs,t is the well-known friendship graph if t = 0, our results …
