You solve diagonals by finding the two perpendicular bases. You do the Pythagorean theorem to find them out.
The diagonal of a rectangle can be found with the Pythagorean Theorem, since
the diagonal is the hypotenuse of the right triangle formed by the sides of the
figure. It is the square root of the sum of the squares of the two sides.
Finding the diagonal of a parallelogram would require some knowledge of trig.,
e.g. the law of cosines, or something equivalent.

How many diagonals does a 44 sided polygon has?
It has 40 diagonals.Improved Answer:-Using the formula for diagonals of a polygon: 0.5*(442-132) = 902 diagonals
What is the formula to determine the number of diagonals in a polygon?
It is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon
What is the formula for the number of diagonals from a vertex?
Number of sides - 2
How many diagonals are there in a 25 sided shape?
There are 275 diagonals in a shape with 25 sides. The formula is n*(n-3)/2
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.
How many diagonals are in a 35 side polygon?
There are 560 diagonals by using the diagonal formula
How many diagonals does a 20 sided polygon have?
It has 170 diagonals by using the diagonal formula
What is the formula for the number of diagonals in a hexagon?
n side polygon has n(n-3)/2 diagonals therefore a hexagon has 9 diagonals
How many diagonals does a 44 sided polygon has?
It has 40 diagonals.Improved Answer:-Using the formula for diagonals of a polygon: 0.5*(442-132) = 902 diagonals
What polygon is involved with 10 diagonals?
None because it does not comply with the formula 0.5*(n2-3n) = diagonals
How many diagonals in 18-gon?
Using the diagonal formula: 0.5*(182-54) = 135 diagonals
How many diagonals in a polygon with 14 sides?
Using the formula: 0.5*(142-42) = 77 diagonals
How many diagonals does a regular 12-gon have?
Using the formula: 0.5*(n2-3n) it has 54 diagonals
What is the formula for the number of diagonals in a nonagon?
For a 9 sided polygon it is: 0.5*(92-(3*9)) = 27 diagonals
What is the formula to find the diagonals of a figure?
1/2*(n2-3n) = diagonals when n equals number of sides.
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.
How many diagonals in triangle to dodecagon?
The formula is: 0.5*(n2-3n) = number of diagonals when n is the number of sides of the polygon
