Which of the letters of the English alphabet have only one line of symmetry ?

Answer

To determine which letters of the English alphabet have only one line of symmetry, we can analyze each letter systematically. A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.

### Step-by-Step Solution:

1. **Understanding Lines of Symmetry**:
- A line of symmetry divides a figure into two identical halves. We can have vertical, horizontal, or diagonal lines of symmetry.

2. **Analyzing Each Letter**:
- **A**: Vertical line of symmetry.
- **B**: Horizontal line of symmetry.
- **C**: No line of symmetry.
- **D**: Horizontal line of symmetry.
- **E**: Horizontal line of symmetry.
- **F**: No line of symmetry.
- **G**: No line of symmetry.
- **H**: Vertical and horizontal lines of symmetry (not included).
- **I**: Vertical and horizontal lines of symmetry (not included).
- **J**: No line of symmetry.
- **K**: Vertical line of symmetry.
- **L**: No line of symmetry.
- **M**: Vertical line of symmetry.
- **N**: No line of symmetry.
- **O**: Infinite lines of symmetry (not included).
- **P**: No line of symmetry.
- **Q**: No line of symmetry.
- **R**: No line of symmetry.
- **S**: No line of symmetry.
- **T**: Vertical line of symmetry.
- **U**: Vertical line of symmetry.
- **V**: Vertical line of symmetry.
- **W**: Vertical line of symmetry.
- **X**: Infinite lines of symmetry (not included).
- **Y**: Vertical line of symmetry.
- **Z**: No line of symmetry.

3. **Listing the Letters with One Line of Symmetry**:
- The letters that have only one line of symmetry are: **A, B, D, E, K, M, T, U, V, W, Y**.

### Final Answer:
The letters of the English alphabet that have only one line of symmetry are: **A, B, D, E, K, M, T, U, V, W, Y**.
