Which statement is true?

A) All squares are rectangles.

B) All quadrilaterals are rectangles.

C) All rectangles are squares.

D) All parallelograms are rectangles.

A; any shape with four sides w / a parallel side across from each other is co soldered a rectangle. It's not b because quadrilaterals just have to have four sides, not be rectangles, it's not c because a square has to have equal length sides and not all rectangles do, and it's not d because a parallelogram only has one set of parallel lines, but a rectangle has to have two.
