WebApr 2, 2024 · In conclusion, a decagon is a polygon with ten sides and angles. It can be either regular or irregular, and its properties include 10 sides, 10 angles, 35 diagonals, and … 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.
