Definitions

• Angle Bisector of a triangle
• The definition of the angle bisector of a
  triangle is a line segment that bisects one of
  the vertex angles of a triangle.
• Perpendicular bisector of a triangle
• A line segment that is both perpendicular to a
  side of a triangle and passes through its
  midpoint.
• Median of a triangle
• A median of a triangle is a line joining a
  vertex to the midpoint of the opposite side. A
  triangle therefore has three medians.
