Question

Lucinda wants to build a square sandbox but has no way of measuring angles. Explain how she can make sure that the samdbox is meansuring only length..

A) Arrange four equal-length sides so the diagonals bisect each other.

B) Arrange four-length sides so the diagonalsare equal in length

C) Make each diagonal the same length as four-length sides

D) This is not possible, Luninda has to be able to measure a right angle.

Answer 1

Option B. Arrange four-length sides so the diagonals are equal in length. Since a square is a rectangle with four equal sides the diagonals should bisect each other at each length and at 90 degrees to each other. This is really important. If the diagonals are equal in length and bisect each other at equal distance then the sandbox is measuring length and has equal angles which is a square by definition
