Write (T) for True and (F) for false:
(iii) A Cone has one vertex.

Answer

To determine whether the statement "A Cone has one vertex" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Cone**:
- A cone is a three-dimensional shape that tapers smoothly from a flat base (which is circular) to a point called the apex or vertex.

2. **Identify the Vertex**:
- The vertex of a cone is the point where the curved surface meets at the top.

3. **Draw a Diagram**:
- To visualize this, draw a cone. Label the circular base and the top point where the cone narrows down to a point (the vertex).

4. **Count the Vertices**:
- In a cone, there is one apex (vertex) at the top and no other points where edges or curves meet.

5. **Conclusion**:
- Since there is only one vertex in a cone, the statement "A Cone has one vertex" is true.

6. **Final Answer**:
- Therefore, we write (T) for True.
