Are rectangles parallelogram because their sides are parallel?
Yes all rectangles are parallelogram but all parallelogram cannot be rectangles.
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.
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
What parallelogram has no right angles?
All of them, except rectangles. (Rectangles are special parallelograms.)
Can a parallelogram also be a rectangle?
Some parallelograms are rectangles; all rectangles are parallelograms.
All squares are rectangles true or false?
True. All squares are rectangles, but not all rectangles are squares.
Are all rectangles rhombuses true or false?
false
Are rectangles parallelogram because their sides are parallel?
Yes all rectangles are parallelogram but all parallelogram cannot be rectangles.
Is every rectangle is a parallelogram?
No. A rectangle is a parallelogram because all of its sides are parallel, but a parallelogram is not a rectangle because it does not have all right angles. It is a true statement to say that all rectangles are parallelograms. However, the statement that all parallelograms are rectangles is false. A parallelogram is a shape where its opposite sides are parallel to each other, including squares, hexagons, octagons, etc.
What property is true for a rectangle but not for a parallelogram?
Rectangles have all right angles. Parallelogram is spelled with an "o".
All rectangles are quadrilaterals true or false?
true
Is it true or false that all squears re rectangles?
True.
Are all squears rectangels true or false?
all squares are rectangles but not all rectangles are squares
Are all rectangles are similar true or false?
false. you can have a 3 by 5 or a 8 by 29
Every parallelogram is a rectangle true or false?
This is false. Every rectangle is a parallelogram, but the converse (your statement) is not true. Imagine the set of all quadrilaterals (4 sided polygons). Within that set would be sets of kites, parallelograms, and other quadrilaterals. Within the parallelogram set, would be rectangles, rhombuses and other parallelograms. Then if a rhombus is also a rectangle, it would be a square, that would be the intersection of the set of rectangles and set of rhombuses. Hope this helps.
