WebA pentagon has 5 diagonals. How many diagonals has a 15-sided polygon? After doing some research, I found out that the number of diagonals of an n -sided polygon = n ( n − 3) 2. This formula works, of course, but the question is one of those in my textbook designated to be solved using combinations. WebMay 3, 2024 · As each diagonal has two ends, there are 10 ⋅ 7 ⋅ 1 2 = 35 diagonals. The approach to the formula you quote is that you pick two vertices to draw a line between, which you can do in ( 10 2) ways. 10 of those are sides of the decagon instead of diagonals, so the result is ( 10 2) − 10 = 35 Share Cite Follow answered May 2, 2024 at 20:58
