Finding the Value of an Angle Using Same Side Interior Angles

The video tutorial explains the concept of parallel lines and transversals, focusing on identifying interior angles. It distinguishes between alternate and consecutive interior angles, emphasizing that consecutive interior angles are supplementary, meaning they add up to 180 degrees. The tutorial includes a practical example of solving for an unknown angle using this property.

Explain the concept of supplementary angles in relation to consecutive interior angles.

What is the equation used to solve for an unknown angle when given a consecutive interior angle?
