👉 Triangle work is a method used in mathematics to solve problems involving triangles. It involves breaking down a problem into smaller, more manageable parts and solving each part individually, then combining them together to find the solution to the original problem. In triangle work, you break down a complex mathematical problem into simpler parts that can be solved independently. Each step of the process helps you understand the structure and relationships within the larger problem, allowing you to build up a more complete picture or solution. Triangular numbers are an
