Web6 years ago. So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A 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 ... WebTo find the number of diagonals in a polygon, we multiply the number of diagonals per vertex ( n − 3) (n-3) (n− 3) by the number of vertices, n n n , and divide by 2 (otherwise each diagonal is counted twice); Therefore, for a 20-sided polygon, there …
