A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted . In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space).

## Why do we need triangular numbers?

Triangular numbers are generally introduced to students using the story of Carl Gauss, a famous mathematician who, as a student, used the idea of the formula for triangular numbers to help him sum consecutive numbers. … They could develop the pattern and be able to explain how to get to the next triangle number.
