How many diagonals are there in an undecagon

WebAnswer (1 of 5): A diagonal of any n-sided regular polygon goes from one vertex to another non-adjacent vertex, of which there are n-3. We must divide by two because diagonals are non-directional. So the formula is \dfrac{n(n-3)}{2} A dodecagon has twelve sides so substituting n=12 we see ... WebHow many pairs of diagonals are there in Decago? You can use a direct formula. Number of diagonals of a polygon of n sides=n (n--3)/2. Put n=10 we get 10*7/2=35 diagonals. A decagon has 10 vertices. Thus C (10,2)=10*9/2=45 lines can be drawn out which includes 10 sides. Hence number of diagonals of a decagon=45–10=35. Hope this works…
