There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
It works out that a polygon with 1175 diagonals has 50 sides
You are a square
Formula: number of diagonals = 1/2 * n(n-3) where n is the number of sides or vertices Example: to get the number of diagonals in a pentagon pentagon has 5 sides or vertices; thus, n = 5 no. of diagonals: = 1/2 * n(n-3) = 1/2 * 5(5-3) = 1/2 * 5(2) = 1/2 * 10 = 10/2 = 5
There are 35 diagonals inside a decagon
38 diagonals
1/2*(142-42) = 77 diagonals
Number of sides minus two equals number of diagonals drawn from one vertex.

rhombus
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 square and a rectangle have diagonals of equal lengths
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
5(5-3)/2. That it is the formula so that shape would have 5 diagonals. n(n-3)/2 where n is the number of 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.
