To determine the property of the diagonals of a rhombus, we need to understand some of the key characteristics of a rhombus:
1. A rhombus is a type of quadrilateral where all four sides have equal length.
2. One of the unique properties of a rhombus is that its diagonals bisect each other at right angles, meaning they intersect at 90-degree angles.
Given this information, the diagonals of a rhombus must be:
- Perpendicular to each other.
Therefore, the correct answer is:
B. perpendicular
