  1. 1-3 Measuring Segments

  2. The distance between points A and B is the absolute value of the difference of their coordinates

  3. Problem 1: Measuring Segment Lengths What is ST? What is UV? What is SV?

  4. Problem 2: Segment Addition Postulate

  5. If EG=59, what are EF and FG?

  6. Problem 3: Comparing Segment Lengths When numerical expressions have the same value, you say they are equal (=). If two segments have the same length, then the segments are congruent () segments

  7. Are congruent? • Is ? • To find AC, could you subtract –2 from 5. Do you get the same result? Why?

  8. Problem 4: Using the Midpoint Midpoint of a segment is a point that divides the segment into two congruent segments Segment Bisector: The point, line, ray, or segment that intersects a segment at its midpoint

  9. Q is the midpoint of . What are PQ, QR, and PR?

  10. U is the midpoint of . What are TU, UV, and TV?
