True or False? All rectangles are squares. 

False

200

Compare and contrast rectangles and squares. How are they similar? How are they different?

Similar: 4 sides, straight sides, 4 angles, all angles are right angles

Different: A square has 4 equal sides, a rectangle has opposite sides that are parallel and of equal length
