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.
