The correct Answer is:
To find the point of intersection of the angle bisectors of a triangle, we can follow these steps: 1. **Understand the Definition of an Angle Bisector**: An angle bisector is a line that divides an angle into two equal parts. In a triangle, each vertex has an angle, and the angle bisector of that vertex will split it into two equal angles. 2. **Identify the Angle Bisectors**: In a triangle, there are three angles, and thus three angle bisectors. Let's denote the triangle as ABC, where A, B, and C are the vertices. The angle bisectors would be: - The angle bisector of angle A (dividing it into two equal angles). - The angle bisector of angle B (dividing it into two equal angles). - The angle bisector of angle C (dividing it into two equal angles). 3. **Locate the Point of Intersection**: The three angle bisectors will intersect at a single point inside the triangle. This point is special because it is equidistant from all three sides of the triangle. 4. **Name the Point**: The point where the three angle bisectors of a triangle intersect is known as the **Incenter** of the triangle. The Incenter is also the center of the circle that can be inscribed within the triangle (the incircle). 5. **Conclusion**: Therefore, the point of intersection of the angle bisectors of a triangle is called the Incenter. ### Final Answer: The point of intersection of the angle bisectors of a triangle is called the **Incenter**. ---
