What We Have Discussed?

independent measurements are required to draw a unique quadrilateral.

A quadrilateral can be constructed uniquely if:

(a) The lengths of four sides and angle are given.

(b) The lengths of sides and one diagonal are given.

(c) The lengths of three sides and diagonals are given.

(d) The lengths of adjacent sides and three angles are given.

(e) The lengths of three sides and two angles are given.

The two special quadrilaterals, namely rhombus and square, can be constructed when diagonals are given.
