   Starting from just a few simple, clearly true rules, you can build, step by step, all of geometry's truth — without assuming anything else.

   Elements

   From simple, self-evident axioms, entire geometry is built through logical steps.

   Euclid started with rules so simple nobody could disagree, like you can draw a straight line between any two points. From these tiny rules, through clear logical steps, he proved hundreds of truths about triangles, circles, and angles. Each step rests only on the ones that came before it.

   “Things which are equal to the same thing are also equal to one another.”
