Solution

The correct option is D

With measure of BC, Yes


We need atleast 5 measurements to construct a unique quadrilateral.

Measurements of 3 angles are given. If we have the measurements of 2 adjacent sides, construction will be possible.

But the lengths of the adjacent sides are not given.

So, if the measurement of either BC or AD is given, construction will be possible.

The correct answer is, yes if the measure of BC is known.
