Angles Formed by Parallel Lines and Transversals

This video tutorial is part 2 of lessons 6-8, focusing on identifying and finding angles formed by parallel lines and transversals. It begins with an introduction to key vocabulary, such as parallel lines and transversals, followed by examples demonstrating how to find the value of X using angle relationships. The tutorial includes practice problems for students to solve on their own, reinforcing the concepts of corresponding and congruent angles.

What is the definition of parallel lines?

• Lines that intersect at one point

• Lines that are perpendicular

• Lines that form a right angle

• Lines that never intersect
