difference of their coordinates

Problem 1: Measuring Segment Lengths

What is ST?

What is UV?

What is SV?

Problem 2: Segment Addition Postulate

If EG=59, what are EF and FG?

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

Problem 3: Comparing Segment Lengths

•Are congruent?• Is ?• To find AC, could you subtract

–2 from 5. Do you get the same result? Why?

Problem 4: Using the MidpointMidpoint of a segment is a point that divides the segment into two congruent segments
