Chapter 1 Section 2 Measuring and Constructing Segments Geometry Chapter 1 Section 2 Measuring and Constructing Segments

Objective You will learn to use the Ruler Postulate, … Copy and compare Segments for congruence, … Use the Segment Addition Postulate.

Vocabulary Postulate/ Axiom A rule in Geometry that is accepted without proof. The real number value that corresponds to the point. S T 5 6 Coordinate The distance between points. It is the Absolute difference between the 2 values of the coordinates. Y Z 7 15 Distance

Construction A geometric drawing that uses a limited set of tools, usually a compass and straightedge. Congruent Segments Segments that have the same length. When 3 points are collinear then one of the points is between the other 2. Between

Vocabulary Postulate/ Axiom A rule in Geometry that is accepted without proof. The real number value that corresponds to the point. S T 5 6 Coordinate The distance between points. It is the Absolute difference between the 2 values of the coordinates. Y Z 7 15 Distance

Ruler Postulate The distance between the points A and B, written AB, is the absolute of the difference of the Coordinates A and B.

Segment Addition Postulate If B is between A and C, then AB + BC = AC. If AB + BC = AC, then B is between A and C.
