No. Consider a quadrilateral with 2 adjacent right angles and the other two angles being 80 and 100 degrees respectively. The two adjacent right angles are congruent, but none of the sides have the same measure.
No. Consider a quadrilateral with three angles that each measure 85 degrees and a 4th angle that measures 105 degrees. Three congruent angles, but not a rectangle.
Key fact to remember is that the sum of the interior angles of a quadrilateral is 360.
