This is because they do not have to be different. So the 4 sides of a rectangle may, or may not be, of equal length. If they are of equal length, then THAT RECTANGLE IS A SQUARE. If the rectangle's 2 pairs of parallel sides are not of equal length then THAT RECTANGLE IS NOT A SQUARE.
Step-by-step explanation:
If you learn geometry, you learn that it is how a rectangle has not equal sides.
Squares are defined by having all equivalent sides. Sometimes, rectangle have different lengths of side, thus not fitting the definition of a square. However, the definition of a rectangle is "an object with 2 pairs of sides parallel to eachother", therefore all squares fit the definition of a rectangle. Please mark brainliest :)
