Does a rhombus have acute and obtuse angles?

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.
