The definition of a parallelogram is that it's a quadrilateral in which both pairs of opposite sides are parallel. So, that part is true about all parallelograms. Apart from that, there are some other properties that can be deduced, such as:
* Opposite sides are congruent
* Opposite angles are congruent
* The diagonals bisect one another
* The sum of the squares of the sides equal the sum of the squares of the diagonals
As well as some other properties.
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
True
Diagonals are congruent
No. This is only true of parallelograms.
False but they are both 4 sided quadrilaterals
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
All rectangles are parallelograms.
The sentence "this shape has five sides" is not true for all parallelograms.
