This document defines and provides examples of different types of angles, including acute, right, obtuse, straight, complementary, supplementary, bisected, vertical, and linear pair angles. It explains that acute angles are less than 90 degrees, right angles are 90 degrees, and obtuse angles are greater than 90 degrees. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. Bisected angles have a line dividing them evenly at the vertex. Vertical angles are the same measure and across from each other at a shared vertex. A linear pair consists of two angles next to each other that share a side and vertex.
