Exploring Parallel Lines and Transversals in Algebra

What is the main focus of objective 3.6 in the video?

• Learning about the Pythagorean theorem

• Using angle relationships in parallel lines cut by a transversal

• Studying the properties of triangles

• Understanding the properties of circles

Why can we set the equation 5x - 10 equal to 3x + 60?

• Because the angles are alternate interior angles

• Because the angles are supplementary

• Because the angles are corresponding angles

• Because the angles are both acute
