This lesson teaches you how to find the length of a line segment from two parts. You will be shown how to add the lengths of each part of the segment in order to get the total length of the segment. This is accomplished by adding the first part of the segment to the second part of the segment. This technique is useful when you are given the lengths of two different parts of a line and need to know the total length.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
