.Which statement is true? A. All squares are rectangles. B. All quadrilaterals are rectangles. C. All parallelograms are rectangles. D. All rectangles are squares.

Directrix (directrix):

A. All squares are rectangles. ----------------------------- A rectangle is a parallelogram with 4 right angles. A square is a parallelogram with 4 right angles and 4 congruent sides. Forget about the sides - because of the 4 right angles, the square qualifies as a rectangle. Note: The following are all FALSE statements: B. All quadrilaterals are rectangles. C. All parallelograms are rectangles. D. All rectangles are squares.

Directrix (directrix):

@Cemantha --> What is your reasoning for that?

OpenStudy (anonymous):

omg now im confused :(

OpenStudy (anonymous):

because how can a square be a rectangle wen odveously a square has equal sides and angles and a rectangle had eaqual angles but not sides.

Directrix (directrix):

Both a square and a rectangle have 4 sides. So both are quadrilaterals. To be a rectangle in the context of this problem, all the square needs to have is 4 right angles. The sides do not matter.
