Finding the Value of x using Alternate Interior Angles
In this lesson, students will learn how to find the value of x using alternate interior angles. To start, parallel lines and a transversal line are needed. The angles on alternating sides of the transversal are called alternating interior angles, which are equal to each other. By setting two x minus fifteen equal to x plus fifty-five, the value of x can be found. In this specific problem, the value of x is seventy. Finally, this value can be used to find the values of the two angles, which are both equal to one hundred and twenty-five degrees.
Finding the value of x using alternate interior angles
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.
- What is a transversal?
- What are alternate interior angles?
- If I have 2 alternate interior angles with measures of 2x-15 degrees and x+55 degrees, then how do I solve for x and find the angle measures?

Staff Review
This lesson explains what alternate interior angles are and what their relationship with one another is. It also shows how to solve for x when you are given the angle measurements of alternate interior angles in terms of x, and it shows how to find the measurement of the angles.
