Inquiries-Week 5: Triangles Emerge
Introduction
In this inquiry, nodes are connected one at a time. How many lines can you draw before a triangle emerges?
Starting with Four
Let's start with four nodes - draw them on a sheet of pap...

Forbidden Subgraph earrings are inspired by Kuratowski's theorem: that it is *impossible* to draw a graph on paper without edges crossing if your graph contains K33 or K5 (left/right). Brass and Bronze versions in stock now at#mathjewelry #graphtheory
