0.5*(172-51) = 119 diagonals
To find the number of sides of a polygon that contains 119 diagonals, we can use the formula for the number of diagonals, which is ( \frac{n(n-3)}{2} = D ), where ( n ) is the number of sides and ( D ) is the number of diagonals. Setting ( D = 119 ), we have ( n(n-3) = 238 ). Solving the quadratic equation ( n^2 - 3n - 238 = 0 ) gives ( n = 17 ) (since ( n ) must be positive). Therefore, a polygon with 17 sides contains 119 diagonals.
It is called a regular polygon.
A ten sided polygon is called a Decagon.
A five-sided polygon is called a pentagon.
The name of a 119 sided polygon is Tetraenneatetragon.
The name of a 119 sided polygon is enneadecahectagon.
A lot. :)Improved Answer:-119

A polygon with 3 sides is called triangle A polygon with 4 sides is called quadrilateral A polygon with 5 sides is called pentagon A polygon with 6 sides is called hexagon A polygon with 7 sides is called heptagon A polygon with 8 sides is called octagon
For a nine side polygon its called a nonagon.For a nine side polygon its called a nonagon.For a nine side polygon its called a nonagon.
That is called a regular polygon.
A polygon with 10 sides is called...
A five sided polygon is called a pentagon because pentagon means five sided polygon I think.
An 8-sided polygon is called an octagon.
It is called a regular polygon.
