Are all parallelograms squares true or false?
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
Are all trapezoids parallelograms true or false?
False but they are both 4 sided quadrilaterals
All parallelograms are rectangles?
False
All rectangles are parallelograms?
True
Which property is not true for all parallelograms?
Diagonals are congruent
Are all parallelograms squares true or false?
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
Is true or false all parallelograms are aquares?
All squares are parallelograms, but all parallelograms are not squares.
Are all trapezoids parallelograms true or false?
False but they are both 4 sided quadrilaterals
There are some parallelograms which are not rectangles true or false?
yes. rectangles are just the special cases of parallelograms where the angles are all 900
Are all squares parallelograms or squares?
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
All parallelograms are rectangles?
False
Parallelograms are squares is that sometimes always or never true?
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.
Is not all rectangles are parallelograms true?
not true
Are all rectangles are parallelograms but not all parallelograms are rectanges true or false?
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.
All rectangles are parallelograms?
True
Is it true that all quadrants are parallelograms?
No.
Are all parallelograms quadrilaterals?
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
