2)The opposite angles of a quadrilateral are congruent, what is the most accurate way to classify this quadrilateral ?
  

3)The bisectors of any two adjacent angles of a parallelogram intersect at
  

4)One of the angle of a parallelogram is twenty four degree less than double the smallest angle. The bigger angle of the parallelogram is
  

5)Measure of one angle of a parallelogram is 2/3 of its measure of the adjacent angle. Measure of the smaller angle of the parallelogram is
  

6)A parallelogram has opposite sides that are:
