May 24, 2016 · Times 10 equals 70; each diagonal is counted twice, so the final answer is 35. Now, using combinations and such: There are (102) ( 10 2) ("10 choose 2") pairs of vertices, which equals 45. So there are 45 line segments joining pairs of vertices. Exactly 10 of those are sides of the decagon, the others are diagonals. Answer: 35. If all the diagonals lie inside the heptagon, it is known as convex heptagon. If some of the diagonals lie outside of the heptagon and one or more interior angles are greater than 180 degrees, then the heptagon is known as concave heptagon. Heptagon Properties Some properties of heptagons are as follows:But since we've counted each one twice, it's really 54 divided by 2, or 27. Generalizing for an n-gon. If you look at our example for a 9 sided figure, you can see how we used the number 9 in our figuring, and we can just substitute n in its place to find the number of diagonals in an n-gon: d = 1 / 2n ( n -3) Instagram:https://instagram. just4u safewaygeometry eoc practice test answerseqsuite provider portalnsfw celeb The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of septua-, a Latin -derived numerical prefix, rather than hepta-, a Greek -derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle.
