Question

It is possible to construct a unique quadrilateral ABCD with AB = 5cm, BC = 6cm, CD = 7cm , $\angle ABC$ = ${45}^{\circ }$ and $\angle BCD$ = ${55}^{\circ }$.

• A. Yes, it is possible
• B. No, two such quadrilaterals can be constructed

Answer 1

The correct option is A

Yes, it is possible

Step 1: Draw AB = 5cm.

Step 2: At B, draw an angle of ${45}^{\circ }$ and mark 6 cm along that angle. Mark the point as C.

Step 3: At C, draw an angle of ${55}^{\circ }$ and mark 7cm along that angle. Mark the point as D.

Step 4: Join point A and D. So, quadrilateral ABCD can be constructed.
