Wheel of Theodorus

Root, Square
Wheel of Theodorus The Wheel of Theodorus is also called the Spiral of Theodorus, the Square Root Spiral, Einstein Spiral, or Pythagorean Spiral. It was first constructed by Theodorus of Cyrene. The smallest triangle is a 1-1-√2 right triangle. Each right triangle after that is formed by using the hypotenuse of the preceding triangle as a leg of the new triangle, adding a leg of size 1 at right angles to that new leg. In this drawing the largest triangle has a hypotenuse of √17. This makes a great MathArt project for students learning about square roots. credit: wikipedia
