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.
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.
Yes, a parallelogram can have two obtuse angles. In a parallelogram, opposite angles are equal and adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, if two angles are obtuse (greater than 90 degrees), the other two angles must be acute (less than 90 degrees) to satisfy the angle sum property.
The Parallelogram Consecutive Angles Conjecture states that the consecutive angles in a parallelogram are supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees. This property follows from the fact that opposite angles in a parallelogram are congruent.
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.
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.
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.
Yes, a parallelogram can have two obtuse angles. In a parallelogram, opposite angles are equal and adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, if two angles are obtuse (greater than 90 degrees), the other two angles must be acute (less than 90 degrees) to satisfy the angle sum property.
A parallelogram is a two-dimensional figure, so it has two dimensions.
A kite is not a parallelogram because the parallelogram's angles are tilted and a kite isn't.
