Because it is the first day working with parallel lines, I make a HUGE deal out of pushing the vocabulary of alternate interior, alternate exterior, etc. If two parallel lines are cut by a transversal, then the two pairs of alternate exterior angles are congruent. 10. corresponding angles 11. alternate exterior angles If the transversal is not perpendicular to the parallel lines, then four angles are acute and four are obtuse. Surface Area and Volume of Cylinders, Cones, and Spheres. • A line that intersects two or more other lines is called a transversal. Use the figure for Exercises 2 and 3. Use the figure for Exercises 10–13.
