no
Not always because 98 degrees and 140 degrees are both obtuse angles that are not congruent but angles 150 degrees and 150 degrees are both obtuse angles that are congruent.
Parallelograms normally have 2 congruent obtuse angles and 2 congruent acute angles that altogether add up to 360 degrees
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.
NOImproved Answer:-Yes a rhombus has equal opposite acute angles and equal opposite obtuse angles
A parallelogram
If it is a 'regular' hexagon, then all angles are congruent, and all are obtuse.

An obtuse triangle must have two acute angles and these can be congruent.
Yes, (with 1 exception) all rhombi will have 2 congruent acute angles, and 2 congruent obtuse angles. The 1 exception is if the rhombus is a square, then all angles will be right angles.
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
obtuse
It is a rhombus
Not always
Learn the definitions. Any angle greater than 90º is obtuse. Two angles are congruent if and only if they are equal. For example, 105º ≠ 150º, but both are greater than 90º; therefore, they are not congruent. Obtuse, fersure!

No, there are different kinds of angles, such as acute, reflex, straight and obtuse. A right angle is 90°.
No. A square is a polygon with four congruent sides and all angles measuring 90 degrees.
