Which of the following is a true statement?
a. all squares are rectangles
b. all rectangles are squares
c. all rhombuses are squares

A rectangle is a parallelogram with interior right angles.
That description applies very satisfactorily to squares.
A square is a special kind of rectangle, so all squares are rectangles.

(All squares are rhombuses, parallelograms, and quadrilaterals too.)
