Write (T) for True and (F) for false:
(i) A Cylinder has no vertex.

Options

A. `" Partially false"`
B. `False`
C. `True`
D. `" Partially true "`

Answer

To determine whether the statement "A Cylinder has no vertex" is true or false, we can analyze the properties of a cylinder.

### Step-by-Step Solution:

1. **Understand the Definition of a Cylinder**:
- A cylinder is a three-dimensional shape with two parallel circular bases connected by a curved surface.

2. **Identify the Characteristics of a Cylinder**:
- A cylinder has two circular bases.
- The sides of the cylinder are curved.

3. **Define a Vertex**:
- A vertex is a point where two or more edges meet. In three-dimensional shapes, vertices are typically found at the corners.

4. **Analyze the Cylinder**:
- Since a cylinder has curved surfaces and its bases are flat circles, it does not have any corners or edges that meet at a point.

5. **Conclusion**:
- Therefore, a cylinder does not have any vertices.

Based on this analysis, we can conclude that the statement "A Cylinder has no vertex" is **True**.

### Final Answer:
**(i) A Cylinder has no vertex: T (True)**
