All the four sides of a rhombus are equal.

Answer

To determine whether the statement "All the four sides of a rhombus are equal" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Definition of a Rhombus**:
- A rhombus is a type of polygon that is a quadrilateral (four sides) with all sides of equal length.

2. **Identifying the Properties**:
- One of the key properties of a rhombus is that all four sides are indeed equal. This means that if you measure each side of a rhombus, they will all have the same length.

3. **Conclusion**:
- Since the definition and properties confirm that all sides of a rhombus are equal, we can conclude that the statement "All the four sides of a rhombus are equal" is **True**.
