which of the following is always true? A. Rectangles are squares. O. Squares are rectangles. O. Parallelograms are squares. Quadrilaterals are rectangles.

Squares are indeed rectangles! Every square meets the definition of a rectangle, which is a four-sided figure with opposite sides equal and all angles being right angles. The tricky part? Not all rectangles can claim the square status—only those with all four sides equal can make that claim. When thinking about shapes, it's helpful to visualize how they fit into a hierarchy. Imagine a family tree of polygons: all squares belong in the rectangle branch, while rectangles can also include those non-square siblings—so keep that in mind next time you draw a rectangle; it might just turn into a square if you adjust the sides!
