Question

a construction worker wants to make sure that an opening for a window is rectangular. if both diagonals measure exactly 37 inches, can the worker be certain that the opening is rectangular? explaiun.

Answer 1

he can't be certain about it completely based on the diagonal length

Explanation:

it is true that rectangle has the property of having equal diagonals but it could be some other quadrilateral with equal diagonals like rhombus so it doesn't guarantee that the opening is rectangular. to determine it he has to verify the additional properties such as measuring the angles of 4corners of the opening. if 4 of them are 90 degrees then it can be concluded that the opening is rectangular.
