A square has four sides of the same length, and four 90 degree angles between them. A rectangle has the angles, but the sides don't necessarily need to be all of the same length. Thus, all squares are rectangles, but not all rectangles are squares, much like thumbs and fingers. In case anyone was wondering :P
A quadrangle is not usually a shape in English. It is a courtyard surrounded by buildings. It does not actually have to be four-sided, but usually is. The correct word is quadrilateral. A rectangle is a quadrilateral (a four-sided polygon) but a quadrilateral can also be some other four-sided shape such as a square or parallelogram. Thus, the quadrilateral and the rectangle are the same shapes in some circumstances.
Quadrilateral is τετράπλευρο in Greek, though. See this image:
So… Το τετράγωνο είναι ένα ορθογώνιο. :)

Is this mathematicaly correct? I mean - if ορθο-γώνιο mean any shape with 4 right angles, then square is part of family ορθογώνιο. Every square is right-angled (but not every right-angled is square).

OK, now I see discussion above, older. I didn't see it in mobile, where I learn, I see it on the web only.
See my comment above, in addition, the Greek sentence does not refer to..."rectangular shape" it simple says..."The square and the rectangle are different shapes."
Trying to interpret the sentence is not the same as translating. Duolingo makes translating easy just follow these tips
