Can a parallelogram have obtuse angles
WebA Parallelogram is a flat shape with opposite sides parallel and equal in length. Opposite angles are equal (angles A are the same, and angles B are the same) Angle A and angle B add up to 180°, so they are supplementary angles. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
