What else can I help you with?
Is not all rectangles are parallelograms true?
not true
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 rectangles parallaelgrams?
All rectangles are parallelograms.
What is true of rectangles that isn't true of parallelograms in general?
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
Is it true that rhombuses are special parallelograms?
Yes, it is true that rhombuses are special types of parallelograms. A rhombus is defined as a parallelogram in which all four sides are of equal length. This means that while all rhombuses are parallelograms, not all parallelograms are rhombuses, as parallelograms can have sides of different lengths. Additionally, rhombuses have the property of having diagonals that bisect each other at right angles.
Is true or false all parallelograms are aquares?
All squares are parallelograms, but all parallelograms are not squares.
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 parallelograms squares true or false?
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
All rectangles are parallelograms?
True
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.
Is it true that all rectangles are parallelograms?
Yes it's true.
Are some parallelograms rectangles?
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
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 rectangles parallaelgrams?
All rectangles are parallelograms.
Which is not true for all parallelogram?
The sentence "this shape has five sides" is not true for all parallelograms.
Which property is not true for all parallelograms?
Diagonals are congruent
