Using the cosine formula in trigonometry the diagonals of the quadrilateral works out as 5.71cm and 6.08cm both rounded to two decimal places
A quadrilateral with diagonals of different lengths can be a rectangle or a kite. In a rectangle, the diagonals are equal in length, while in a kite, the diagonals are not equal and intersect at right angles. Other quadrilaterals, like trapezoids and irregular quadrilaterals, can also have diagonals of different lengths. Therefore, many quadrilaterals can fit this description, depending on their specific properties.
A parallelogram with sides whose lengths are half the diagonals of the original quadrilateral.
No because a kite is a 4 sided quadrilateral with two diagonals of different lengths that intersect each other at right angles.
The converse of the rectangle diagonal conjecture states that if the diagonals of a quadrilateral are equal in length, then the quadrilateral is a rectangle, which implies that its corners are right angles. To test if the corners of a quadrilateral are right angles, measure the lengths of the diagonals. If the diagonals are equal, you can conclude that the corners are right angles, confirming that the shape is a rectangle.
A quadrilateral has four sides with lengths, two diagonals with lengths, four inside angles, four outside angles, and an area. The angles are the only things you can measure with a protractor.

No because a kite is a 4 sided quadrilateral with two diagonals of different lengths that intersect each other at right angles.
Only rectangles (squares included) have congruent diagonals, because all their angles are congruent (90 degrees). If you have angles larger or smaller than 90 degrees it makes the diagonals different lengths.

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)
A quadrilateral has four sides with lengths, two diagonals with lengths, four inside angles, four outside angles, and an area. The angles are the only things you can measure with a protractor.
A quadrilateral as described is a parallelogram. If the angles between the two sets of parallel lines are 90 degrees, the shape is a rectangle, a special form of parallelogram.
A kite is a quadrilateral that is named thus because of it's kite-like appearance. It has two pairs of sides with equal lengths that are adjacent and congruent. The diagonals of a kite intersect at ninety degrees. See the 'related link' for a picture.
The given vertices when plotted on the Cartesian plane forms a rectangle with diagonals of square root of 50 in lengths and they both intersect at (3.5, 4.5)
If you mean quadrilateral ABCD then by using the cosine rule diagonal AC equals 5.71 cm and diagonal BD equals 6.08 cm both rounded to two decimal places.
