Webpaper, we start with basic graph theory and proceed into concepts and theorems related to planar graphs. In the last section we will give a proof of Kuratowski’s theorem, which in general corresponds with that in Graph Theory with Applica-tions (see [1] in the list of references) but provides more details and hopefully more clarity. 2.
