1-3 Measuring
The distance between points A and
B is the absolute value of the
difference of their coordinates
Problem 1: Measuring Segment
What is ST?
What is UV?
What is SV?
Problem 2: Segment Addition
If EG=59, what are EF and FG?
Problem 3: Comparing Segment
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
• Are 𝐴𝐶 𝑎𝑛𝑑 𝐵𝐷 congruent?
• Is 𝐴𝐵 𝑐𝑜𝑛𝑔𝑟𝑢𝑒𝑛𝑡 𝑡𝑜 𝐷𝐸?
• To find AC, could you subtract
–2 from 5. Do you get the
same result? Why?
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
Q is the midpoint of 𝑃𝑅. What are
PQ, QR, and PR?
U is the midpoint of 𝑇𝑉. What are
TU, UV, and TV?
