1. **Problem Statement:** Find the angle formed between the diagonals of a rhombus. 2. **Key Properties:** A rhombus is a quadrilateral with all sides equal in length. Its diagonals bisect each other at right angles (90 degrees). 3. **Formula and Explanation:** The diagonals of a rhombus intersect at right angles, so the angle between the diagonals is always 90 degrees. 4. **Reasoning:** Since the diagonals bisect each other perpendicularly, the angle formed between them is a right angle. 5. **Final Answer:** The angle formed between the diagonals of a rhombus is $$90^\circ$$.
