Solution
The correct option is A True To construct a parallelogram, we draw a triangle with the given measurements. Then, we find the fourth vertex using the measurements of the adjacent sides. Hence, three independent measurements are necessary to construct a parallelogram. We are given the lengths of 2 diagonals and the angle between them, which is enough to construct a unique trapezium.
