Lucinda wants to build a square sandbox, but she has no way of measuring angles. Which of the following explains how she can make sure the sandbox is square by measuring only length?

Question

anonymous · Answer

Make sure all four sides are the same length, then make sure both diagonals are the same.

anonymous · Answer

The first step ensures it is a rhombus, the second confirms that rhombus is a square.

anonymous · Answer

Arrange four equal-length sides, so the diagonals bisect each other.
Arrange four equal-length sides, so the diagonals are equal lengths also.

Not possible; Lucinda has to be able to measure a right angle.
