If measure of sides of a quadrilateral are given as AB = 4cm, CD = 5cm, and angles are given as ∠ABC=75∘,∠BCD=45∘and∠CDA=135∘, then what additional information is required to construct a quadrilateral ABCD?
BC
We can't draw a unique quadrilateral with all the measurements which are given. This is because we need the measurement of two adjacent sides and 3 angles to construct the quadrilateral ABCD. But with BC, we will have 6 sets of measurements and two known adjacent sides. Hence, we will be able to construct the quadrilateral ABCD.
