Question

ayeli wants to build a square picture frame but she has no way of measuring the angles. If she can only measure with a ruler, how can she make sure the picture frame will be square? Option 1 Arrange four sides of equal lengths so that the diagonals are also equal lengths. Option 2 Arrange four sides of equal lengths so that the diagonals bisect each other. Option 3 No possible, she has to be able to measure a right angle. Option 4 Make each diagonal the same length as four equal length sides

Answer 1

Option 2 is the correct answer. By arranging four sides of equal lengths so that the diagonals bisect each other, Ayeli can ensure the picture frame is square without measuring the angles. This method relies on the fact that in a square, the diagonals bisect each other at right angles.
