Which letters of the English alphabet have :
a single horizontal line of symmetry

Answer

To determine which letters of the English alphabet have a single horizontal line of symmetry, we can follow these steps:

### Step 1: Understand Horizontal Line of Symmetry
A horizontal line of symmetry means that if you draw a horizontal line through the middle of a letter, the top half will mirror the bottom half.

**Hint:** Visualize or draw the letters to see if they can be split into two equal halves horizontally.

### Step 2: Analyze Each Letter
We will examine each letter of the English alphabet to see if it has a horizontal line of symmetry.

1. **B**: If you draw a horizontal line through the middle of B, the top half (the upper loop) mirrors the bottom half (the lower loop).
2. **C**: A horizontal line through the middle of C will show that the top part curves similarly to the bottom part.
3. **D**: The top half of D mirrors the bottom half when divided horizontally.
4. **E**: The three horizontal lines of E are symmetrical about a horizontal line drawn through the middle.
5. **H**: H has two vertical lines and a horizontal line in the middle, making it symmetrical about that horizontal line.
6. **K**: The upper part of K mirrors the lower part when divided horizontally.

### Step 3: List the Letters
Based on our analysis, the letters that have a single horizontal line of symmetry are:
- B
- C
- D
- E
- H
- K

### Final Answer
The letters of the English alphabet that have a single horizontal line of symmetry are B, C, D, E, H, and K.
