A parallelogram has the 2 pair of opposite congruent sides, but a rectangle (special case of parallelogram) also has the four congruent angles.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
If both pairs of opposite angles of a quadrilateral are congruent, then it is a parallelogram.
Yes
True
a parallelogram
false; if both pairs
A quadrilateral characterized by opposite sides that are congruent and opposite angles that are congruent is a parallelogram. In a parallelogram, both pairs of opposite sides are equal in length, and both pairs of opposite angles are equal in measure. Common examples of parallelograms include rectangles, rhombuses, and squares, which also have additional properties.
A parallelogram.
A rectangle.
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.
