Geometry 1-2 Measuring and Constructing Segments

Vocabulary coordinate- the number a point corresponds to on a ruler coordinate- the number a point corresponds to on a ruler The distance is the length between two points. Distance is always positive. The distance is the length between two points. Distance is always positive. AB = a – b or b - a A a B b

Example 1: Finding the Length of a Segment Find each length. Must be positive, so BC=2 A. BCB. CA = -2 BC = 1 – 3 CA= 5 = 5 CA = 3 – (-2)

Congruency PQ  RS Congruent segments are segments that have the same length. Tick marks are used in a figure to show congruent segments.

Segment Addition Postulate First part + Second Part = Whole length First part + Second Part = Whole length

Example 1 G is between F and H, FG = 6, and FH = 11. Find GH. F G 11 6 H Example 2 M is between N and O. NM = 17, MO = 3X-5, and NO = 5x + 2. Find the length of NO.

Definition of Midpoint Bisect- to cut into two congruent parts. Bisect- to cut into two congruent parts. Midpoint- A point that bisects a segment. If M is the midpoint of AB, then AM = MB. Midpoint- A point that bisects a segment. If M is the midpoint of AB, then AM = MB. So if AB = 6, then AM = 3 and MB = 3. So if AB = 6, then AM = 3 and MB = 3. MB A 33 6 midpoint
