Yup; as long as the opposing sides are parallel -- it can be a parallelogram. Technically, a rectangle is a parallelogram too.
True
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
yes, it is true
yes. rectangles are just the special cases of parallelograms where the angles are all 900
Yes.
True when they are in the form of rectangles.
True. All squares are rectangles, but not all rectangles are squares.
False
All rectangles are parallelograms.
No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.
Oh, dude, like technically speaking, all rectangles are trapezoids, but not all trapezoids are rectangles. It's like saying all squares are rectangles, but not all rectangles are squares. So, yeah, some trapezoids can be rectangles, but not all of them. It's like a geometry mind game, man.
