In a rhombus, what can be said about the opposite angles?

• A. They are always different
• B. All angles are right angles
• C. They are equal
• D. Some angles are obtuse

Answer: (C)

In a rhombus, opposite angles are always equal. This property is a defining characteristic of a rhombus, which is a type of parallelogram. A rhombus not only has opposite angles that are equal, but adjacent angles are supplementary, meaning they add up to 180 degrees. For instance, if one angle measures 60 degrees, the angle directly opposite to it will also measure 60 degrees, while the other two angles will both be 120 degrees, as they need to add up to 180 degrees with their adjacent angles. This relationship helps to ensure that the shape maintains its structure and symmetry. Understanding this property can aid in solving various geometric problems related to rhombuses, such as calculating missing angle measures or proving congruence between shapes.
