Write the letters of the English alphabet which have only one line of symmetry.

Answer

To determine which letters of the English alphabet have only one line of symmetry, we will analyze each letter step by step. A letter can have either a vertical line of symmetry, a horizontal line of symmetry, or both. We are looking for letters that possess only one of these types.

### Step-by-Step Solution:

1. **Identify the letters of the alphabet**: The English alphabet consists of 26 letters: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

2. **Check each letter for symmetry**:
- **A**: Has a vertical line of symmetry.
- **B**: Has a vertical line of symmetry.
- **C**: Has a vertical line of symmetry.
- **D**: Has a vertical line of symmetry.
- **E**: Has a vertical line of symmetry.
- **F**: No line of symmetry.
- **G**: No line of symmetry.
- **H**: Has both vertical and horizontal lines of symmetry.
- **I**: Has both vertical and horizontal lines of symmetry.
- **J**: No line of symmetry.
- **K**: Has a vertical line of symmetry.
- **L**: No line of symmetry.
- **M**: Has a vertical line of symmetry.
- **N**: No line of symmetry.
- **O**: Has both vertical and horizontal lines of symmetry.
- **P**: Has a vertical line of symmetry.
- **Q**: No line of symmetry.
- **R**: Has a vertical line of symmetry.
- **S**: No line of symmetry.
- **T**: Has a vertical line of symmetry.
- **U**: Has a vertical line of symmetry.
- **V**: Has a vertical line of symmetry.
- **W**: Has a vertical line of symmetry.
- **X**: Has both vertical and horizontal lines of symmetry.
- **Y**: Has a vertical line of symmetry.
- **Z**: No line of symmetry.

3. **List letters with only one line of symmetry**:
- The letters that have only one line of symmetry (either vertical or horizontal) are:
- A
- B
- C
- D
- E
- K
- M
- P
- R
- T
- U
- V
- Y

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