Abstract: - This paper is a brief discussion about Pascal’s triangle and the patterns found within it. Pascal’s triangle is a very famous construction, that many students have learned about. What is less talked about though is the patterns found within Pascal’s triangle, including number and geometrical patterns. The patterns discussed in this report are combinations, binomial expansion coefficients, polygonal numbers, and the Fibonacci sequence.

Key-Words: - Pascal, Pascal’s triangle, triangular numbers, binomial expansion

1 Introduction
Pascal’s triangle is one of the most famous mathematical patterns, known to most students. Pascal’s triangle is a sequence of numbers, arranged in rows that form a triangle, with the following properties: …show more content…

Many different patterns can be found in Pascal’s triangles, including both number patterns as well as geometrical patterns, and this report will discuss a few of these number patterns.

2 History
This triangle is most commonly known as Pascal’s triangle in America, after the French mathematician Blaise Pascal, who wrote about it in 1653. Although Pascal investigated this triangle thoroughly, he was not the discoverer of this triangle. Many other mathematicians have described this triangle, such as Al-Karaji in Persia around 980, Jia Xian in China in the 11th century, Yang Hui in China in the 13th century, and more [6]. Thus, around the world, Pascal’s triangle has various names, named after the other mathematicians. This type of misattribution is unfortunately common in mathematics and science.

3 Common Usage
Two of the most common usages in modern schools, is using the relationship between Pascal’s triangle and binomial coefficients, and combinations. Students often use Pascal’s triangle, to easily find the coefficients of binomial expansion, or the solutions to counting principles including combinations, by writing out the triangle. Since the construction of the triangle is easy, requiring only sums, students can easily use it to find these numbers, instead of using the
