This describes a rectangle. It has four sides, four right angles, and its opposite sides are parallel, but the adjacent sides are not equilateral (congruent). If a quadrilateral has four right angles, it will be either a square or a rectangle. With the four right angles, it cannot be anything else. Draw a line segment. Now draw another one at a right angle to the first one. Now draw a third line segment at a right angle from the second one, and make this one the same length as the first one. Then draw the last segment to close the figure. It will have fours sides, and it will have four right angles. It will also have two pairs of parallel sides.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
Yes, it is.
Parallelograms have 4 sides, it is a quadrilateral with the opposite sides parallel, and the opposite angles are congruent.4
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
Every parallelogram is.

A parallelogram is a quadrilateral with opposite sides parallel and congruent.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
False. If both pairs of opposite angles of a quadrilateral are congruent 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.
Yes, it is.
