WebIn geometry, a triacontagon or 30-gon is a thirty-sided polygon. The sum of any triacontagon's interior angles is 5040 degrees. Regular triacontagon [ edit] The regular triacontagon is a constructible polygon, by an edge- bisection of a regular pentadecagon, and can also be constructed as a truncated pentadecagon, t {15}. WebNov 8, 2014 · Note that it is always less than or equal to n ( n − 1) ( n − 2) ( n − 3) 24 because in an ideal case when each intersection point is corresponding to a unique pair of diagonals (not two or more pairs) then by choosing 4 vertexes of n we will have two diagonals and this pair of diagonals determines an intersection point and this point is not an …
WebNumber of diagonals in polygons of n sides = n (n-3)/2. Here, n (n-3)/2 = 35, or n (n-3) = 70 So n = 10. So a decagon has 35 diagonals. 360/10 = 36. So sum of all interior angles = (!80–36)*10 = 144*10 = 1440 deg. 1440/180 = 8. So at any one vertex we can draw 8 diagonals and thus form 8 triangles at each vertex. More answers below WebSolution: The number of diagonals of a polygon of n sides, is given by n (n-3)/2. Here, n = 13, so the 13-gon has 13 (13–3)/2 = 65 diagonals. Answer. 3 Sponsored by Grammarly …

Sorted by: 2. (1) There is a bijection between diagonals and pairs of non-adjacent vertices of the n -gon. There are ( n 2) pairs of vertices altogether, of which n pairs consist of adjacent vertices, so there are ( n 2) − n pairs of non-adjacent vertices the same number of diagonals. If you want, you can expand this to get rid of ...
WebSep 7, 2024 · How many vertices are there in a 42-gon? How many diagonals are in a 42-gon? A diagonal can go to any vertex except the one it starts at and the two neighbors, so there are 39 destinations for each of the 42 starting points. This gives a total of \(42\cdot39 = 1638\) “directed diagonals”; dividing by 2, we have 819 diagonals.
