geometry chapter 6 vocab

• perpendicular bisector - line that is perpendicular to a segment at its midpoint

  1. makes a right angle
  2. intersects at the midpoint
• circumcenter - the point of concurrency for perpendicular bisectors
• angle bisector - ray that divides an angle into 2 congruent adjacent angles

  1. divides an angle into 2 equal angles
• incenter - the point of concurrency for angle bisectors
• median - segment from vertex to the midpoint of the opposite side

  1. starts at a vertex
  2. meets the midpoint of the opposite side
• centroid - the point of concurrency for medians
• altitude - perpendicular segment from a vertex to the opposite side or a line that contains the opposite side (height)

  1. forms a right angle
  2. starts at a vertex
• orthocenter - the point of concurrency for altitudes
