## What is PythagorasTree?

The Pythagoras Tree is math art.  A square trunk is drawn.  The hypotenuse of a right triangle is laid on top of the square.  From the two legs two new squares are drawn.  This process is repeated recursively until there the size of the square is too small to draw.  Here you can adjust the angles of the triangle and the color of the tree.  You can also make the tree grow and shrink to see the steps in making the tree.

## Key features

- Recursive fractal generation
- Adjustable triangle angles
- Customizable tree colors
- Interactive growth and shrink animation
- Visualizes Pythagorean theorem

### 5/5 — Best app ever!

*2011-05-27, version 1.1*

This is my new fave app! I could play with it for hours! The only suggestion i have is a reset button, to take the tree back to its original color, angle, and size......

### 5/5 — Educational yet, Entertaining

*2011-02-28, version 1.0*
