Proving Lines Parallel with Algebra

The video tutorial covers various angle pairs, including corresponding, alternate interior, alternate exterior, and consecutive interior angles. It explains how these angles relate to parallel lines and demonstrates using algebra to find the value of X that proves lines are parallel. The tutorial includes multiple examples to illustrate these concepts, emphasizing the congruence and supplementary properties of angle pairs.

What is the relationship between corresponding angles when two lines are parallel?

• They are equal to 90 degrees.

• They are complementary.

• They are congruent.

• They are supplementary.
