B. 3
C. 6
D. 9

Answer

To solve the question "How many parts does a triangle have?", we will analyze the components of a triangle step by step.

### Step-by-Step Solution:

1. **Understanding the Triangle**: A triangle is a polygon with three edges and three vertices. It is formed by connecting three points in a plane.

2. **Identifying the Parts**: A triangle has two main types of parts:
- **Sides**: These are the straight lines that form the triangle. A triangle has three sides.
- **Angles**: These are the corners formed by the sides. A triangle has three angles.

3. **Counting the Parts**:
- **Number of Sides**: 3 (Side AB, Side BC, Side CA)
- **Number of Angles**: 3 (Angle A, Angle B, Angle C)

4. **Total Parts in a Triangle**: To find the total number of parts, we add the number of sides and angles together:
- Total Parts = Number of Sides + Number of Angles
- Total Parts = 3 (sides) + 3 (angles) = 6 parts.

5. **Selecting the Correct Option**: Based on the options provided:
- Option 1: 2
- Option 2: 3
- Option 3: 6
- Option 4: 9

The correct answer is **Option 3: 6**.

### Final Answer:
The triangle has **6 parts** in total.
