How to... Solve Puzzles | Showing All 20 Triangles Created from 6 Intersecting Straight Lines - Step by Step Solution @howto...solvepuzzles | Uploaded 5 years ago | Updated 8 hours ago
This video shows where all 20 triangles are located on a shape made from 6 intersecting straight lines. There is a simple formula that shows how to calculate the maximum number of triangles. This formula is n!/(3! x (n-3)!) When n = 6, then the answer is 20 triangles. However, nothing that I read showed where all 20 triangles were located, so I set about to find all twenty triangles and this videos shows exactly where the 20 triangles are located.
