Draw a semi circle and find the number of lines of symmetry it has.

Answer

### Step-by-Step Solution:

**Step 1: Draw a semicircle.**
- To draw a semicircle, start by drawing a straight horizontal line. This will be the diameter of the semicircle.
- Use a compass or a round object to draw a curve that connects the endpoints of the diameter, forming a half-circle above the line.

**Step 2: Identify the line of symmetry.**
- A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.
- For a semicircle, the line of symmetry is the vertical line that runs down the center of the semicircle, perpendicular to the diameter.

**Step 3: Check for additional lines of symmetry.**
- To determine if there are any other lines of symmetry, consider folding the semicircle along different lines.
- You will find that the only line along which the semicircle can be folded to match both halves is the vertical line through the center.

**Step 4: Count the lines of symmetry.**
- Since we have identified only one line of symmetry, we conclude that the semicircle has exactly one line of symmetry.

### Final Answer:
The semicircle has **1 line of symmetry**.
