False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
False but they are both 4 sided quadrilaterals
yes. rectangles are just the special cases of parallelograms where the angles are all 900
false. a parallelogram has both opposite side parallel
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.
False. All rhombuses are parallelograms, so all rhombuses have 2 pairs of parallel sides.
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
That is true. A parallelogram is a quadrilateral with both pairs of opposite sides parallel to one another. Special types of parallelograms include a rhombus (all four sides also congruent to each other), a rectangle (all four interior angles measure 90o), and a square (all four sides congruent and all four interior angles are right). A rectangle is a special case of a parallelogram, therefore all rectangles are by definition parallelograms but not all parallelograms are rectangles.
