1/2*(142-42) = 77 diagonals
how many diagonals are there iin a polygon of 11 sides
120*(120-3)/2 = 7020
In a polygon with ( n ) sides, the number of diagonals that can be drawn from one vertex is given by the formula ( n - 3 ). For a polygon with 35 sides, this means you can draw ( 35 - 3 = 32 ) diagonals from one vertex. Thus, from one vertex in a 35-sided polygon, you can draw 32 diagonals.
That polygon is called a "triangle". It has no diagonals.
A polygon with 14 diagonals will have 7 sides
38 diagonals
how many diagonals are there iin a polygon of 11 sides
In a 54-sided polygon, 53 possible diagonals can be drawn from one vertex to another. These diagonals will not intersect. Therefore, the interior will be divided into 54 regions by the 53 diagonals plus the two sides of the original polygon that adjoin the vertex from which the diagonals are drawn.
In a polygon with n sides, the number of diagonals that can be drawn from one vertex is given by the formula (n-3). Therefore, in a 35-sided polygon, you can draw (35-3) = 32 diagonals from one vertex.
120*(120-3)/2 = 7020
That polygon is called a "triangle". It has no diagonals.
64 sides = 64 angles From one angle you can draw (64 - 2) diagonals = 62. Lines from an angle to the immediately adjacent angles are sides, not diagonals.
A 7 sided polygon has 14 diagonals
There are 77 diagonals
An heptagon has 7 sides and 14 diagonals
It is 18 diagonals
It will have ten sides
