In this lesson we are going to learn about measuring segments. An important postulate we'll learn about is the ruler postulate: The points on any line can be paired with real numbers so that, given any two points P and Q on the line, P corresponds to zero, and Q corresponds to a positive number. You'll see how this postulate actually helps us define the measure of a segment, and you'll get to practice that through examples. Also, you'll learn about the segment addition postulate, the Pythagorean theorem and the right triangles, and the Distance formula.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
