3-1 Objectives Distinguish between intersecting lines, parallel lines, and skew lines. Identify the angles formed when two lines are cut by a transversal. Practice using your textbook as a resource.

Lines that do not intersect Two lines that do not intersect are either parallel or skew

Lines and Planes Can two planes be parallel? Can a line and a plane be parallel?

Names of Angles Interior Angles: Exterior Angles: Corresponding Angles: Alternate Interior Angles: Same-Side Interior Angles:

Example Name a transversal line: Identify each pair of angles: ∠5 and ∠3: ∠7 and ∠3: ∠6 and ∠3: ∠8 and ∠6:

Self-guided notes Use p. 73-74 in your textbook to complete the self-guided notes on your own or with a partner.

Your book does not mention this but… It is also possible to define: Alternate exterior angles: Same-side exterior angles:
