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
Vertical angles can be either acute, obtuse, or right, depending on the measures of the angles formed by the intersecting lines. If the angles measure less than 90 degrees, they are acute. However, if they measure more than 90 degrees, they are obtuse. Therefore, a pair of vertical angles can be acute, but this is not always the case.

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.
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.
No
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
No, vertical angles are not a linear pair. Vertical angles are formed when two lines intersect, creating pairs of opposite angles that are equal in measure. A linear pair consists of two adjacent angles that sum to 180 degrees and share a common side. While vertical angles may be supplementary to other angles, they are not adjacent and do not form a linear pair.

no
Yes, a pair of intersecting lines always forms a pair of vertical angles.
