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.

Whenever two lines intersect, vertical angles refers to the angles opposite each other
false
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
In every pair of complementary angles, both of them are acute angles.
No
A rhombus has a pair of opposite equal acute angles and a pair of opposite equal obtuse angles and the four angles add up to 360 degrees.
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.

The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
Yes, a pair of intersecting lines always forms a pair of vertical angles.
