1-3 Segments and Their Measures

In this section you will learn about segments and how to find the distance between two given points. There are a few different ways to find the measure of a segment. One of the ways is to use the segment addition postulate. another way is to use the ruler postulate or the distance formula.In the textbook, this section is from page 17 to page 25.

coordinate-a real number that corresponds to a point

Distance Formula-a formula for computing the distance between two points on a coordinate plane

congruent segments-segments that have the same length

Ruler Postulate- The distance between one point to another, is the absolute value of the difference between the two coordinates

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

Distance Formula-When you measure the distance between two points you use the formula below
