Term
 perpendicular bisector
Definition
 of a segment is a line, a ray, or even a plane that is perpendicular to a segment at mid point.
Term
 perpendicular bisector theorem
Definition
 if a point is on the perpendicular bisector of segment, then it is equidistant from the endpoints of a segment.
Term
 angle bisector
Definition
 if a point is on the bisector of an angle, then the point is equidistant from the angle
Term
 angle bisector theorem
Definition
 if a point in the interior of an angle is equidistant from the sides of the angle, then angle the point is on the angle bisector
Term
 Perpendicular bisector of a triangle
Definition
 is a line that is perpendicular to a side of a triangle at the sides of midpoint
Term
 concurrent
Definition
 three or more line intersect at one point
Term
 point of concurrency
Definition
 point which the intersect
Term
 concurrency of perpendicular of bisector
Definition
 the perpendicular bisector of the side of a triangle are concurrent at point equidistant from the vertices
Term
 circumcenter of a triangle
Definition
 the point of concurrency of the perpendicular bisector of this triangle
Term
 Circumcenter of acute triangle
Definition
 inside of the triangle
Term
 Circumcenter of right triangle
Definition
 on the hypotenuse of the triangle
Term
 circumcenter of obtuse triangle
Definition
 outside the triangle
Term
 angle bisector triangle
Definition
 is a bisector of an angle of the triangle split the angle in half
Term
 Concurrency of angle bisector theorem
Definition
 the bisector of the angles of a triangle are concurrent at a point equidistant from the sides of the triangle
Term
 incenter of the triangle
Definition

Term
 median of a triangle
Definition
 is a segment whose endpoints are a vertex and the midpoint of the opposite side. a triangle three median are always cuncurrents
Term
 conccurrency of the median theorem
Definition
 the median of a triangle are at a point the is two thirds the distance form each vertex to the midpoint of the opposite sides
Term
 altitude of a triangle
Definition
 is the perpendicular segment form a vertex of a triangle to the line containing opposite sides. can be inside or outside the triangle to it can be a side of a triangle
Term
 concurrency of altitudes theorem
Definition
 the lines that contain the altitudes of a triangle are concurrent
Term
 Orthocenter of a triangle
Definition
 the orthocenter of a triangle can be inside,on, or outside the triangle
