How many diagonals does a n gon have
WebAug 10, 2024 · Number of Diagonals = n (n-3)/2 In other words, an n-sided polygon has n-vertices which can be joined with each other in nC2 ways. Now by subtracting n with nC2 ways, the formula obtained is n (n-3)/2. For example, in a hexagon, the total sides are 6. So, the total diagonals will be 6 (6-3)/2 = 9. How many degrees is a 17 Gon? WebSep 5, 2024 · The answer is simply $\binom{n}{4}$, because a set of four vertices of the polygon uniquely determines a pair of intersecting diagonals, and therefore (by the "three diagonals" condition) their intersection point.
