It has two pairs of parallel sides.
Its adjacent angles are supplementary.
The base length of a parallelogram is larger than its width or its side.
No as for example the diagonals of a rectangle are equal in length whereas they are not equal in length in a parallelogram
No, a parallelogram has two dimensions.
No, as the angles of a square are all equal, whereas the angles of a parallelogram typically aren't. There are other examples, as well; this is just one difference.
All the angles being 90o. A rectangle, like a parallelogram, has two pairs of parallel sides and opposite angles equal; however a rectangle also requires that the angles are all 90o (right angles) unlike a general parallelogram.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.
The base length of a parallelogram is larger than its width or its side.
No as for example the diagonals of a rectangle are equal in length whereas they are not equal in length in a parallelogram
Rectangles have all right angles. Parallelogram is spelled with an "o".
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
No, a parallelogram has two dimensions.
No, as the angles of a square are all equal, whereas the angles of a parallelogram typically aren't. There are other examples, as well; this is just one difference.
All the angles being 90o. A rectangle, like a parallelogram, has two pairs of parallel sides and opposite angles equal; however a rectangle also requires that the angles are all 90o (right angles) unlike a general parallelogram.
A parallelogram is a two-dimensional figure, so it has two dimensions.
