In geometry, the spiral of Theodorus (also called the square root spiral, Pythagorean spiral, or Pythagoras's snail) is a spiral composed of right triangles, placed edge-to-edge. It was named after Theodorus of Cyrene .
Apr 16, 2024 · A square root spiral looks like this. We follow these steps to form it. Mark a center point O. From point O, draw a horizontal line OA of length 1 cm. From point A, draw a perpendicular line AB of length 1 cm. Join OB, here OB = √2. Now, from point B, draw a line perpendicular to OB (Use set squares) of length 1 cm. Mark the end point as C.

Oct 14, 2021 · The square-root spiral is attributed to Theodorus, a tutor of Plato. It comprises a sequence of right-angled triangles, placed edge to edge, all having a common point and having hypotenuse lengths equal to the roots of the natural numbers. The spiral is built from right-angled triangles.
