Say true or false :
The centre of a circle is always in its interior.

Answer

To determine whether the statement "The centre of a circle is always in its interior" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Circle**:
- A circle is defined as the set of all points that are at a fixed distance (radius) from a central point (the center).

2. **Identify the Center of the Circle**:
- The center of the circle is the point from which all points on the circle are equidistant.

3. **Define the Interior of a Circle**:
- The interior of a circle refers to all the points that are inside the circle, which are closer to the center than the radius.

4. **Visualize the Circle**:
- If we draw a circle, we can see that the center is located at a point that is not on the boundary but rather inside the circle.

5. **Conclusion**:
- Since the center of the circle is indeed located inside the circle and not on the boundary, we can conclude that the statement is true.

### Final Answer:
The statement "The centre of a circle is always in its interior" is **True**.
