There is no general formula. You could use basic trigonometry.
You measure it. If you know the lengths of two other sides, as well as the angle between them, you can also use the law of cosines.
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
The square has a diagonal measurement of: 1.13 km
Two of them
A kite is a quadrilateral because it has four sides. In addition, two of its opposite sides are congruent (equal in length), which is a defining characteristic of a kite.
The diagonal length is about 20.59
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
It is a rhombus or a kite
Any quadrilateral that is not a parallelogram can have only one diagonal that is bisected by the other.
The square has a diagonal measurement of: 1.13 km
A square
Square
You would have to consider a triangle formed by one diagonal and two sides of the quadrilateral. If you know the lengths of these sides, and the measure of the angle between them, you can use the cosine law to find the diagonal. c2 = a2 + b2 -2ab(cosC)
No. It could be a kite.
In this case, the quadrilateral is sometimes a parallelogram.
Two of them
a quadrilateral in which diagonal are not congruent and larger diagonal is perpendicular bisector of smaller diagonal then it is known as kite
The diagonal measurement of an 8 ft square is: 11.31 feet.
