“When dealing with a square, the first three angles will be 90 degrees, the fourth usually isn’t.”

How is that possible? The sum of the angles of any quadrilateral must equal 360 degrees. If three angles are 90 degrees, the fourth must be 90 degrees. For one of the angles to be 89 degrees, the 1 degree must be made up in one or more of the remaining angles. Granted, 90 1/3 degrees is difficult to measure. You eyes may not recognize that a quadrilaterial with three 90 1/3 angles and one 89 degree angle is not square. But, it is not geometrically possible to have a quadrilateral with three 90 degree angles and one 89 degree angle.

Maybe I am reading this too literal.
