What has two pairs of parallel sides with two acute angles and obtuse angles?
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
What is a quadrilateral with two pairs of opposite equal parallel sides and four right angles?
rectangle
What is a quadrilateral with two pairs of opposite sides that are equal and parallel and has four right angles?
A rectangle
If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is not a parallelogram?
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
If one side of a quadrilateral is congruent to its opposite side then the quadrilateral is a parallelogram?
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.
Are the angles in a quadrilateral opposite or adjacent?
- Opposite angles are two angles that don't share a side. A quadrilateral has two pairs of them. - Adjacent angles are angles that share one side. A quadrilateral has four pairs of them.
How do you describe the angles and sides of each quadrilateral?
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
What ia a parallelogram?
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
What is a quadrilateral with only two pair of opposite sides parallel?
I would be seriously concerned if a quadrilateral had more than two pairs of opposite sides parallel! A quadrilateral with two pairs of opposite sides parallel is a parallelogram.
What is a quadrilateral with two pairs of parallel and opposite sides and opposite angles congruent?
A parallelogram. A rhombus, rectangle and square are special cases of a parallelogram.
What is a quadrilateral with no right angles and both pairs of opposite side parallel and equal in length?
A rhombus. Commonly referred to as a "diamond".
A parallelogram is a quadrilateral in which both pairs of opposite sides are paraellel?
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
