Lesson Summary:

Learn how to solve for x and y in a trapezoid using alternate interior angles and supplementary angles. By extending lines to create parallel lines, you can determine alternate interior angles and corresponding angles. With this information, you can set up equations and solve for the values of x and y in the trapezoid.

Lesson Description:

Finding the value of x using a trapezoid alternate interior angles and supplementary 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.

    This lesson shows how you can find angle measurements using alternate interior angles. The problem in the lesson also gives a couple of the angle measurements in terms of x and y, and the lesson shows how to solve for x and y.
