Theodorus Spiral


Welcome to the Draw a Theodorus Spiral tool! This tool allows you to generate a spiral based on Theodorus's sequence of right triangles.

Steps to Use the Tool:

  1. Number of Triangles: Enter the desired number of triangles to be drawn to form the spiral.
  2. Draw Spiral: Click the "Draw Spiral" button to generate the Theodorus spiral based on your input.


  • Dynamic Generation: The tool dynamically generates the Theodorus spiral based on the specified number of triangles.
  • Real-time Visualization: As you adjust the number of triangles, the spiral updates in real-time, providing instant feedback.
  • Customizable: Users can customize the number of triangles to create different variations of the Theodorus spiral.


  • Visualization: Provides a visual representation of the Theodorus spiral, showcasing the unique pattern formed by successive right triangles.
  • Mathematical Exploration: Ideal for students and enthusiasts interested in exploring mathematical sequences and their geometric representations.
  • Educational Tool: Offers an interactive way to learn about Theodorus's sequence and its application in creating spirals.


  • Q: What is Theodorus's Spiral?
    • A: Theodorus's Spiral is a spiral composed of consecutive right triangles, where each triangle has legs of lengths 1 and the hypotenuse of the previous triangle as its other side.
  • Q: How does the number of triangles affect the spiral?
    • A: Increasing the number of triangles results in a denser spiral, while decreasing it produces a sparser spiral with fewer turns.
