Abstract

In this article, I study the problem of counting the number of triangles formed in a triangle if n segments are drawn from one vertex to its opposite side, and h segments are drawn from another vertex to its opposite side. This kind of counting problem is often seen in puzzle collections; e.g.: “Count the number of triangles visible in Figure 1”. Making a manual count for such a problem is tedious; also, it is easy to make an error in the count. We need a more analytic and systematic procedure.
