Lucinda wants to build a square sandbox, but has no way of measuring angles. explain how she can make sure that the sandbox is square by only measuring length.
select one:
a. arrange four equal-length sides so the diagonals are equal lengths also.
b. make each diagonal the same length as four equal-length sides.
c. not possible; lucinda has to be able to measure a right angle.
d. arrange four equal-length sides so the diagonals bisect each other.

Answer with explanation:

Properties of Square

1. All sides are equal.

2. Each of the interior angle as well as exterior angle is a right angle.

3.Diagonals bisect each other at right angles and are equal in Length.

4.Opposite sides are Parallel.

Lucinda wants to build a square sandbox, but has no way of measuring angles. She can make  the sandbox in the shape of square by measuring length in the following way:

Option A: Arrange four equal-length sides so the diagonals are equal lengths also.

→→→Among all the quadrilaterals, square and rhombus ,are those quadrilaterals,whose all sides are equal,but it is Quadrilateral Square, only whose diagonals are equal in length.
