Question

The minimum number of measurements needed to construct a square is

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is A $1$

Properties of square $:$

$1.$ All four sides of square are equal.

$2.$ Measure of each of four angles is ${90}^o.$

So, considering above two properties of square, we only required measure of one side of square since all sides are equal to construct a square.

$\therefore$ The minimum number of measurement needed to construct a square is $1.$
