## How does the Sierpinski triangle work?

All of this leads to a more precise definition of the Sierpinski Triangle: it is a self-similar fractal that results from removing the triangle connecting the three midpoints of an equilateral triangle’s sides, and continuing this process for the resulting equilateral triangles within that triangle.

### What is special about the Sierpinski triangle?

The Sierpinski triangle is a fractal described in 1915 by Waclaw Sierpinski. It is a self similar structure that occurs at different levels of iterations, or magnifications. We can use Geometer’s Sketchpad to construct these types of triangles, and then compare them to the pattern of Pascal’s Triangles.

**Why is the Sierpinski triangle important?**

This idea of triangular similarity is especially important in the case of the gasket because if we realize that each subtriangle of the gasket is, itself, actually another gasket with the same relative properties as the original gasket.

**What is the recursive pattern in the triangle?**

Recursively, triangular numbers are found by adding the previous term to the nth term of the sequence. This sequence goes on forever. The odd number pattern of Pascal’s triangle shows an image that appears to look like Sierpinski’s gasket.

## What is recursion in C?

Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function. The C programming language supports recursion, i.e., a function to call itself.

### Where is Sierpinski triangle used?

**Why is Sierpinski triangle important?**

**Is the Sierpinski triangle a recursive case?**

Making midpoints – and midpoints of midpoints – has a distinctly recursive smell to it. But before we get to the recursive case, let’s look at what it will have to address. For instance, to complete our order 1 Sierpinski triangle, we have to draw the remaining two triangles within the confines of our order 0 triangle.

## How to draw a Sierpinski triangle in Python?

The first thing sierpinski does is draw the outer triangle. Next, there are three recursive calls, one for each of the new corner triangles we get when we connect the midpoints. Once again we make use of the standard turtle module that comes with Python.

### Which is the best example of recursion in programming?

Recursion is a programming technique that involves creating functions that recall themselves. Most problems that can be solved with looping can also be solved with recursion. A popular demonstration of recursion is Sierpinski’s Triangle. This image below shows a fifth order Sierpinski’s Triangle.

**How big is the perimeter of the Sierpinski triangle?**

Briefly, the Sierpinski triangle is a fractal whose initial equilateral triangle is replaced by three smaller equilateral triangles, each of the same size, that can fit inside its perimeter.
