This lesson covers the concept of parallel lines in geometry, focusing on the properties and relationships of angles formed by parallel lines and a transversal. It introduces corresponding angles, interior and exterior angles, and explores their relationships, such as alternate and same-side angles. The lesson also includes solving for unknown angles using algebraic methods, emphasizing the importance of understanding angle pair relationships.

What is the measure of corresponding angles when two parallel lines are crossed by a transversal?

• They are always equal.

• They are always supplementary.

• They are always right angles.

• They are always complementary.

Which of the following pairs are same side interior angles?

• Angles on opposite sides of the transversal and outside the parallel lines.

• Angles on the same side of the transversal and outside the parallel lines.

• Angles on opposite sides of the transversal and inside the parallel lines.
