It could be a hexagon which is stretched out so that one pair of opposite angles become acute - but they must be different otherwise you will have three pairs of parallel sides.
Congruent.
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
A parallelogram or a rhombus
It could be a hexagon which is stretched out so that one pair of opposite angles become acute - but they must be different otherwise you will have three pairs of parallel sides.
A rhombus (pushed over square) will give you 2 pairs of parallel, congruent sides, 2 acute angles and 2 obtuse angles.
Parellelogram
Its sides are congruent but not its angles because it has 2 equal opposite acute angles and 2 equal opposite obtuse angles.
NOImproved Answer:-Yes a rhombus has equal opposite acute angles and equal opposite obtuse angles
A parallelogram has 2 equal opposite acute angles and 2 equal opposite obtuse angles.
It is a rhombus that fits the given description.
No, but the opposite angles are congruent because it has 2 equal opposite acute angle and 2 equal opposite obtuse angles that all add up to 360 degrees.
Yes, a rhombus can have both acute and obtuse angles. A rhombus is a quadrilateral with all sides of equal length, but its angles can vary. Since the opposite angles of a rhombus are congruent, if one angle is acute (less than 90 degrees), then the opposite angle will also be acute. Similarly, if one angle is obtuse (greater than 90 degrees), then the opposite angle will also be obtuse.
