False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
True
No. This is only true of parallelograms.
False but they are both 4 sided quadrilaterals
No trapezoids are parallelograms, and no parallelograms are trapezoids.
They are quadrilaterals; opposite sides are parallel.
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
All squares are parallelograms, but all parallelograms are not squares.
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.
not true
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
True
No.
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
In fact, some are rectangles, but not all are.
Yes it's true.
yes. rectangles are just the special cases of parallelograms where the angles are all 900
