S3 have managed to write a formula for the number of triangles in an nrow triangle. Got my little ones on task and ready for their lesson. Challenging for a class of year 8's, but fun. Mrs Myers' Year 8 gang! It did take us a while though! I have used with every class I teach. I have used it with nearly all of my groups and they all got focussed on the task in hand really quickly.

Highly recommended! The students enjoyed it. There are 2 coming from the 2 vertical sides that were not counted. A great mental exercise. It might be a same counted triangle looked from another perspective. Where exactly are the two missing triangles?

How Many Triangles Are There? Here’s How to Solve the Puzzle
The caveat, evident in looking the diagram, is that no two lines are parallel, and there are no points where more than two lines intersect. The challenge, ideally, was to figure out a procedure to calculate the answer, not to count carefully. I did not reveal the answer, although I did provide a major hint from Dr. So if I have six lines, then the whole question becomes how can I pick three lines out of those six lines? Other readers just tried to count, an almost hopeless task. Loh said. Sign up for the Science Times newsletter. To solve the problem, start with this observation: Any three lines in the diagram define one and only one triangle. It follows that the total number of triangles will be equal to the number of threeline combinations that can be chosen from a group of six lines.
