1/2*(602-180) = 1710 diagonals
1/2*(142-42) = 77 diagonals
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
A shape with four sides and perpendicular diagonals is called a rhombus. In a rhombus, all sides are of equal length, and the diagonals bisect each other at right angles. Additionally, the diagonals are not necessarily of equal length, which distinguishes a rhombus from a square.
A trapezoid has two diagonals. These diagonals connect the non-parallel sides of the trapezoid, intersecting each other inside the shape. Since a trapezoid has four vertices, the number of diagonals can be calculated using the formula ( n(n-3)/2 ), where ( n ) is the number of sides; for a trapezoid, this results in two diagonals.
It works out that a polygon with 1175 diagonals has 50 sides
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.
There is none. A 5 sided shape is a pentagon but that has 10 diagonals, not 2.
A diamond shape has four sides, so it is essentially a quadrilateral. The formula for calculating the number of diagonals in a quadrilateral is (n)(n-3)/2, where n is the number of sides. In this case, n = 4, so the calculation would be (4)(4-3)/2 = 2 diagonals. Therefore, a diamond shape could have 2 diagonals drawn within it.

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
