WebA heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from before and add another 180, (or another triangle), getting us 1,080 degrees. So we can use this pattern to find the sum of interior angle degrees for even 1,000 sided polygons. WebThe number of diagonals of a nonagon is equal to 27.

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… WebQuadrilaterals can only have 1 such diagonal. Drawing in the other one would intersect the first one, and they're called "non-intersecting" for a reason. If we take a pentagon, we can draw 2 diagonals that don't intersect. The key is to draw just enough to separate the polygon into all into triangles.
