WebSep 13, 2024 · First, I counted all the vertices of the hexagon and its diagonals' intersection points (Here 19) and tried to choose 3 points from the (19C3). Then, each diagonal has 5 points on them and there are 5 diagonals. So, there should be 5* (5C3) ways that I am overcounting as they don't make any triangle. My answer is : 19C3 - 5* (5C3). WebCalculate the number of diagonals: The number of diagonals in an n sided polygon is given as, D n = n (n-3) 2. A hexagon has 6 sides, i.e., n = 6. Thus, the number of diagonals in a …
