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 rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
To determine if it is possible to draw a quadrilateral given four side lengths, you can use the triangle inequality theorem. The theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. If this condition is met for all combinations of three sides using the given side lengths, then it is possible to construct a quadrilateral. If the sum of the lengths of any two sides is equal to or less than the length of the third side for any combination, then it is not possible to draw a quadrilateral with those side lengths.
Four line segments can always form a quadrilateral, as long as none of them is longer than the sum of the lengths of the other three,
Four lengths indicate that the figure is a quadrilateral. Unfortunately, quadrilaterals are not rigid so that a set of four lengths can give rise to infinitely many shapes with infinitely many areas. This is on the same principle that a quadrilateral with four equal sides can be a square or a very thin rhombus.
