Here's a more simple answer (about the operative part): Other than the length of the sides, there is no difference between the oblong and perfect square. It's just an old-fashionedy way of referring to a rectangle.Other than the length of one side...What is the difference between the Oblong Square and the Perfect Square? Operatively and Speculatively?
Ummm..... you are half way there......Yes, I'd say that an oblong square = a rectangle. The angle is still 45 degrees, a right angle, but in the oblong square one side is longer than the other. I'll have to think more about the speculative significance of the difference between the two.
