Question

What are the minimum number of parameters required to construct a square?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A

1

Only 1 parameter is sufficient to construct a square because all angles of the square are equal to ${90}^{\circ }$ and all sides are equal in length. So specifying the length of any side fulfills all the criteria.
