SAT: Lines and angles Quiz

Lines, line segments, angles, and (less frequently) rays, are found throughout the SAT. Lines extend infinitely in two directions, while segments are finite. Rays extend infinitely in one direction. All lines have 180 degrees. You need to be familiar with parallel and intersecting lines, including those that intersect at right angles (90 degrees). Angles are formed by the intersection of lines, etc., and you should be familiar with vertical, supplementary, and complimentary angles.
