A tetra-decagon is a 14 sided polygon having 77 diagonals
How many diagonals in decagon have?
35
How many diagonals are there in a decagon?
A decagon has 35 diagonals. A Nonagon has 27 diagonals. An Octagon has 20 diagonals. A Heptagon has 14 diagonals. A Hexagon has 9 diagonals. A Pentagon has 5 Diagonals. A Square has 2 Diagonals. A triangle has 0 Diagonals.Do you get the point?0+2+3+4+7+8. Starting with the triangle.you don't need to start with the triangle because it is 0 diagonals and will not count when you add it up anyways. And don't call it a square, call it a quadrilateral.Shut up-------Imagine a hexagone-There are two vertices at the top which make a horizontal line- Opposite them there are 2 vertices on the bottom which we can draw straight lines totherefore-There would have been 6 connections per point, but we eliminated 3(n-3)---The connections occur for every vertex in the shapethereforen(n-3)--We don't want to draw the same connections twice once we get around to vertices on the opposite side of the shapethereforen/2(n-3)where n is the number of facesThis may be applied to many if not all polygons. A Decagon has 36 sides not 35...There are 35 diagonals in a 10 sided decagon
What is the number of triangles formed in a decagon when all the diagonals from one vertex are drawn?
8
How many diagonals in nonagon and decagon?
it depends on what you mean by a diagonal. If you take a diagonal to mean a line from one corner to the "opposite" corner, then a nonagon doesn't have any, and a decagon has five. The reason a nonagon doesn't have any, is that the corners aren't opposite each other.

How many line segmants are in a decagon?
A decagon has 10 sides and 35 diagonals
How many diagionals does a decagon have?

How many diagonal in a regular decagon?

How many diagonals does a 2d decagon have?
54 Diagonals. * * * * * A polygon with n sides has 1/2*n*(n-3) diagonals. So a decagon would have 1/2*10*7 = 35 diagonals. How the Community answer got 54 is anybody's guess!
What polygon has 20 diagonals?
decagon
How many triangles are formed by drawing diagonals from one vertex in a decagon?
There are 8
How many diagonal lines can be in a ten sided figure?
A decagon has 35 diagonals
What is the total number of diagonals in a decagon?
It is: 0.5*(10 squared - (3*10)) = 35 diagonals
