CHAPTER 1

SECTION 5

SEGMENTS AND THEIR MEASURES

GOAL: MEASURE SEGMENTS AND ADD SEGMENT LENGTHS

A coordinate is a real number that corresponds to a point.

The distance between points A and B is written AB. It is the

absolute value of the difference of the coordinates of A and B.

If AB = 8 and AC = 13 then find the length of BC.

Segments that have the same length are congruent segments.

The length AB is equal to the length of CD. AB = CD

The segment AB is congruent to segment CD. AB CD
