Segment Addition Postulate

• AB+BC=AC

• A line, ray, or segment in the plane of an angle that divides the angle into two congruent angles.

  m<1 + m<2 = m<ABC

• The middle point of the line segment. It is equidistant from each endpoint of the segment and divides the segment into two congruent segments.

  M is the midpoint of AB so AM = MB

• Angles are opposite angles that share a common vertex, formed by two intersecting lines.

Midpoint
