A rectangle is a quadrilateral with four right angles. A square is a particular case of rectangles where all four sides are equal. Therefore, all squares are rectangles, but not all rectangles are squares.

It would be helpful if you told us what aspect of this confuses you. It may well be a language issue; your grammar here is incorrect (you presumably mean "is [every] square a rectangle"), but even correct grammar can be easily misunderstood. You may also be unfamiliar with the way definitions work in mathematics (or science), where, for example, we can say that a cat is a mammal but a mammal may not be a cat.

I discussed some of these issues here.
