How do you find the number of sides of two polygon given the number of diagonals?

Your question is quite confusing because you used the phrase 'two polygon'. When asking mathematical or geometrical questions about shapes you ask about a single specific thing . I assume you meant to ask, '----number of sides of various different polygons, given the number of diagonals in each of them.' I have been drawing polygons with 5 and 6 and 7 and 8 sides and discovering the number of diagonals which can be drawn inside each of them , does not seem to follow a simple formula. I will look into it further and see if I can post you an answer in a day or two. Very interesting question I must say. Hope I can solve it .
Additional Information:-
The diagonal formula for any polygon is: 1/2*(n2-3n) = number of diagonals
Rearrange the formula into a quadratic equation and solve it for a positive value which will be the number of the sides of the given polygon

What is the formula for the sides of a polygon if the diagonals are given?
1/2*(n2-3n) = number of diagonals Rearranging the formula: n2-3n-(2*diagonals) = 0 Solve as a quadratic equation and taking the positive value of n as the number of sides.
What are the number of sides if the polygon has 95 diagonals?
There is no such polygon that fits the given information.
How many sides are there in the polygon if the number of diagonals is twice as the number of sides?
A 7 sided polygon has 14 diagonals
Which polygon has number of sides is equal to the number of diagonals?
The five sided Polygon has 5 diagonals
What is the relationship between the number of sides of a polygon and the number of diagonals?
Number of diagonals = 1/2*(n2-3n) where n = the number of sides of the polygon.
How do you find the number of sides of a polygon given the number of diagonals?
Using the formula (x)(x-3)/2 = Diagonals ; simply replace the diagonals with the number of diagonals you're given. Then, you'll havev (x)(x-3)/2 = Diagonals. Simplify it, and you'll be given x(power of 2) - 3X = (2)(Diagonals). Subtract the amount of diagonals from both sides, and you'll have x(power of 2) - 3X - 2Diagonals = 0. From there, use the quadratic formula to find the number of sides the polygon has.
