Using corresponding angles to show two lines are parallel - Free Math tutorial

The video tutorial explains how to determine if two lines are parallel by examining same side interior angles. If these angles are equal, the lines are parallel. The instructor demonstrates setting up an equation to find the value of X that makes the angles equal, thus confirming the lines are parallel when X equals 1.2.

How can we determine if two lines are parallel using angles?

What is the theorem that relates same side interior angles to parallel lines?

What values need to be equal for the two angles to indicate parallel lines?

Explain the steps taken to solve for X in the equation given.

What is the value of X that makes the two angles equal?
