Finding the Value of X to Prove Two Lines are Parallel

The video tutorial covers the relationships between different types of angles, focusing on interior angles, consecutive interior angles, and alternate interior angles. It explains how to solve equations involving these angles, using properties like supplementary angles and linear pairs. The tutorial demonstrates solving for variables X and Y by applying these geometric principles.

What is the sum of consecutive interior angles?

• 360 degrees

• 45 degrees

• 180 degrees

• 90 degrees

When are alternate interior angles equal?

• When lines are skew

• When lines are intersecting

• When lines are parallel

• When lines are perpendicular
