WebSep 7, 2016 · Diagonals of a Regular Octagon. An octagon is any eight-sided polygon, and the sum of its angles is 1080°, as we saw above. In a regular octagon, each angle = 1080°/8 = 135°. That angle is the supplement of a 45° angle. The regular octagon is the typical stop sign shape in many parts of the world.

WebJun 25, 2024 · So, sum of interior angles of a hexagon = 4 * 180 = 720 and each interior angle will be 120 . Now, we have to find BC = 2 * x. If we draw a perpendicular AO on BC, we will see that the perpendicular bisects BC … WebDiagonals of Polygons. a square (or any quadrilateral) has 4 (4−3)/2 = 4×1/2 = 2 diagonals. an octagon has 8 (8−3)/2 = 8×5/2 = 20 diagonals. a triangle has 3 (3−3)/2 = 3×0/2 = 0 diagonals. shonee fairfax divorce
How to find the length of the diagonal of a hexagon - High School …
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 ... WebApr 10, 2024 · The number of diagonals of a polygon depends on the number of sides it has. There is a simple formula to determine the number of diagonals in a polygon. Number of diagonals= (n(n-3))/2; where n is the number of vertices of the polygon. Example- To calculate the number of diagonals of a hexagon, we take n=6 (because it has 6 vertices) WebSep 7, 2024 · The question apparently is "How many diagonals does a polygon with n sides have?" You have remembered the first formula correctly: it is n(n-3)/2. One way to see this is to notice that you can draw (n-3) diagonals from every vertex of the polygon. This is because there are (n-1) other vertices, but two of them are adjacent vertices and so don't ... shonee
