Triangle Centers

An angle bisector is a line or ray that divides an angle into two congruent angles.

The point of concurrency created is called the Circumcenter.

Perpendicular bisectors are drawn to find the circumcenter.

A median is a line segment that connects a vertex of the triangle to the midpoint of the opposite side.

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

The point of concurrency formed by the medians is called the Centroid.

The Incenter is the point where the angle bisectors of a triangle intersect.

The Orthocenter is the point where the altitudes of a triangle intersect.

A perpendicular bisector is a line that divides a segment into two equal parts at a right angle.

A midsegment is a segment that connects the midpoints of two sides of a triangle.
