Suppose, we have to draw a quadrilateral. The length of three given sides are 'a' units, 'b' units and 'c' units. The measure of two given angles is $\alpha$ and $\beta$. 
The first step is to construct a line segment AB = 'a' units. Taking AB as the base, we construct a line making an angle $\alpha$ with the line segment AB. We cut the line by an arc of length 'b' units taking B as center and mark point where arc cuts the line as C.
Taking BC as the base, we construct a line making an angle $\beta$ with the line segment BC. We cut the line by an arc of length 'c' units taking C as center and mark point where arc cuts the line as D. 
The final step is to join A and D to complete the quadrilateral ABCD.
