Question

What is the minimum number of measurements required to construct a unique rhombus?

___

Answer 1

Since all the sides of a rhombus are equal to each other, even if we know one side, it implies that we have the data of all the sides.

Now, while constructing the rhombus, suppose that we have drawn one side. To draw another side, we need to know at least one angle.

In total, we need at least 2 measurements (1 side and 1 angle) to construct a unique rhombus.
