Question

We can construct a square only if we know the measure of

• A. its one side
• B. its one diagonal
• C. its one side or one diagonal
• D. none of the above

Answer 1

The correct option is C its one side or one diagonal

If we know the side of a square then using the property sides of a square are equal and each angle is ${90}^{\circ }$, we can construct it.

If we know one diagonal of a square using the property diagonals of a square are equal and bisect each other at right angles, we can construct it.
Hence (c).
