Lesson Summary:

In this lesson, we learn how to solve word problems involving the lengths of a triangle. The first step is to read the problem in its entirety and determine what the question is asking. Next, we choose a variable to represent the smallest side of the triangle and define the other sides in terms of that variable. Then, we write an equation using the perimeter of the triangle and solve for the variable. Finally, we use the value of the variable to find the lengths of all sides of the triangle. The key takeaway is to approach word problems systematically and use only one variable to solve them.

Solving word problems lengths of a triangle

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.
