A quadrilateral is a parallelogram if one pair of opposite sides are equal and parallel
Let ABCD be a quadrilateral in which ABCD and AB=CD, where means parallel to.
Construct line AC and create triangles ABC and ADC.
Now, in triangles ABC and ADC,
AB=CD (given)
AC = AC (common side)
Angle BAC=Angle ACD
(corresponding parts of corresponding triangles or CPCTC)
Triangle ABC is congruent to triangle CDA by Side Angle Side
Angle BCA =Angle DAC by CPCTC
And since these are alternate angles, ADBC.
Thus in the quadrilateral ABCD, ABCD and ADBC.
We conclude ABCD is a parallelogram. var content_characters_counter = '1032';

A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel

A parallelogram.
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
That quadrilateral is known as a 'parallelogram'.
Yes, sides are equal in length as well.
In the U.S., that is a specific kind of "trapezium", which is a quadrilateral with no parallel sides.AnswerA quadrilateral with no parallel sides and no equal sides is basically just that, a quadrilateral.
