This document discusses various types of angles including right angles which are 90 degrees, acute angles which are less than 90 degrees, obtuse angles which are greater than 90 degrees, linear pairs which are two angles whose non-shared sides form a straight line, supplementary angles which are two angles whose sum is 180 degrees, complementary angles which are two angles whose sum is 90 degrees, adjacent angles which are two angles that share a common side and vertex, opposite rays which are two rays extending from the same point on opposite sides of a line, and that all angles on a straight line or plane add up to 180 degrees and 360 degrees respectively.
