Auxiliary lines. to find unknown angle measures Jun 14, 2016 · PARALLEL LINES Make sure you know how to identify the different types of angles formed when two lines are cut by a transversal: The angle pairs {2, 8} and {3, 7} are alternate interior angles—you can remember this because they form a sort of “Z” shape or reversed “Z” shape. The angle pairs {1, 2}, {4, 7}, {5, 8}, and {3, 6} are Aug 08, 2019 · Parallel Lines Project Showcase & Student Presentations: Vocabulary. Parallel lines: two or more lines that lie in the same plane and never intersect. Transversal: a line that intersects two distinct lines. These two lines may or may not be parallel. Slope: a number that describes both the direction and the steepness of the line. Assessment
