Chapter 5 Types of Segments

Angle Bisector Bisector of an angle Divides the angle into 2 congruent angles

Median of a Triangle Segment whose endpoints are a vertex and the midpoint of the opposite side midpoint

Altitude of a Triangle Height of a triangle Perpendicular segment from a vertex to the opposite side (must form a right angle)

Perpendicular Bisector Line, ray, or segment that is perpendicular to a segment at its midpoint Must form a right angle and divide segment into 2 congruent parts. Perpendicular Bisector

Perpendicular Bisector of a Triangle a segment (line or ray) that is perpendicular to a side at its midpoint
