Segment Addition Postulate Explained

This video tutorial focuses on line segments, introducing the segment addition postulate and congruent segments. It explains the difference between line segment notation and measurement, and provides examples to apply the segment addition postulate. The video also covers the concept of a midpoint and segment bisectors, with practical examples to enhance understanding.

What does the notation 'AB' without a bar over it represent?

• A point

• The length of a line segment

• An angle

• A line segment
