Sometimes, because they both have two angles.
It is always true because two congruent angles that are complementary both measure 45 degrees.
Two angles are complementary when they add up to exactly 90 degrees. An obtuse angle is by definition greater than 90 degrees. Therefore, an obtuse angle cannot have a complementary angle. So an obtuse angle and an acute angle are never complementary.

sometimes... * * * * * No, never. Two angles are complementary angles if their measures sum to 90 degrees. An obtuse angle has a measure in the range (0, 90) degrees so two of them cannot sum to 90 degrees.

A rhombus does not have right angles. A square always has right angles.
