complementary anglestwo angles whose sum measures 90 degrees
line segmentan infinite number of points that has two distinct end points
supplementarytwo angles whose sum measures 180 degrees
rayan infinite set of points that starts at a point and goes on forever
obtuse anglean angle whose measure is greater than 90 degrees and less than 180
bisectto cut into two congruent parts
linean infinite number of points that goes on forever in both directions
acute anglean angle whose measure is greater than 0 degrees and less than 90 degrees
