Question:
To construct a unique parallelogram, the minimum number of measurements required is
(a) 2
(b) 3
(c) 4
(d) 5
Solution:
(b) We know that, in a parallelogram, opposite sides are equal and parallel. Also,
opposite angles are equal.
So, to construct a parallelogram uniquely, we require the measure of any two non-parallel sides and the measure of an angle.
Hence, the minimum number of measurements required to draw a unique parallelogram is 3.
