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 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.
