## point of concurrency Chapter 6 (p. 300)

### In mathematics, a point of concurrency refers to a specific point where three or more lines, rays, or line segments intersect or coincide

In mathematics, a point of concurrency refers to a specific point where three or more lines, rays, or line segments intersect or coincide. It is the point where these geometric objects meet and share a common intersection.

There are several notable types of points of concurrency that are commonly studied in geometry:

1. Incenter: The incenter is the point of concurrency for the angle bisectors of a triangle. An angle bisector is a line that divides an angle into two congruent (equal) angles. The incenter of a triangle is equidistant from the three sides of that triangle.

2. Circumcenter: The circumcenter is the point of concurrency for the perpendicular bisectors of a triangle. A perpendicular bisector is a line that divides a line segment into two equal parts at a right angle. The circumcenter is equidistant from the three vertices of the triangle.

3. Centroid: The centroid is the point of concurrency for the medians of a triangle. A median is a line segment that joins a vertex of a triangle to the midpoint of the opposite side. The centroid is located two-thirds of the distance from each vertex to the midpoint of the opposite side.

4. Orthocenter: The orthocenter is the point of concurrency for the altitudes of a triangle. An altitude is a perpendicular segment from a vertex of a triangle to the line containing the opposite side. The orthocenter does not always lie inside the triangle; it can also be located outside or on the triangle.

5. Intersection of perpendicular bisectors: When two line segments intersect at a right angle, the point of intersection is the point of concurrency of the perpendicular bisectors. This point is equidistant from the endpoints of the line segments.

Understanding these points of concurrency can aid in solving geometric problems, properties, and constructions involving triangles. They offer insights into the relationship between various geometric elements and can provide important information about the characteristics of a triangle.
