The number of arcs made by a chord on a circle is___

Options

A. 3
B. 2
C. 1
D. 4

Answer

To determine the number of arcs made by a chord on a circle, follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Chord**:
A chord is a straight line segment whose endpoints lie on the circumference of the circle. For example, let's denote the endpoints of the chord as point A and point B.

2. **Draw the Circle and the Chord**:
Start by drawing a circle. Then, draw a chord connecting points A and B on the circle's boundary.

3. **Identify the Arcs**:
When a chord is drawn, it divides the circle into two distinct parts. Each part is known as an arc.

4. **Count the Arcs**:
The chord AB creates two arcs:
- The arc that goes from point A to point B in one direction (let's call it Arc AB).
- The arc that goes from point A to point B in the opposite direction (let's call it Arc BA).

5. **Conclusion**:
Therefore, the number of arcs made by a chord on a circle is **2**.

### Final Answer:
The number of arcs made by a chord on a circle is **2**.
