How many diagonals does a 12-gon have

WebApr 8, 2024 · Now, there are a total of 55 diagonals possible for an 11-sided polygon which includes its sides also. So, subtracting the sides will give the total number of diagonals contained by the polygon. So, total diagonals contained within an 11-sided polygon = 55 -11 which is equal to 44. Formula Method: WebOct 6, 2016 · So your 20 sided polygon (called an icosagon). 20 vertices. you can't draw from the vertex to itself or either of the 2 consecutive vertices....leaving 17 vertices from each vertex. So 20vertices * 17 diagonals divided by 2 for the repetitions = 170 diagonals.
