What quadrilateral is two pair of opposite angle congruent?
Parallelogram
Is a rectangle a special quadrilateral?
A rectangle is defined as "a parallelogram with one right angle" A parallelogram is defined as "a quadrilateral with opposite sides equal and parallel" This makes a rectangle a sort of second-generation quadrilateral!
Can a quadrilateral abcd be aparallelogram if angle d plus angle b equals 180?
Yes, a quadrilateral ABCD can be a parallelogram if angle D plus angle B equals 180 degrees. In a parallelogram, opposite angles are equal, and consecutive angles are supplementary (their sum equals 180 degrees). Therefore, if angle D and angle B are supplementary, it is consistent with the properties of a parallelogram. Thus, the condition does not contradict the definition of a parallelogram.
What is a quadrilateral with opposite sides parallel and congruent and no right angle?
It is a rhombus or a parallelogram

Parallelogram
Does a parallelogram have a 90 degree angle?
No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
What is a quadrilateral with two pairs of parallel and congruent sides?
A rhombus, or a square if there is a 90o angle.
