This topic focuses on understanding and identifying relationships between angles within different geometric configurations. Skills practiced include recognizing complementary angles that sum to 90 degrees, supplementary angles that sum to 180 degrees, and identical angles (equal angles). Additionally, there are problems addressing pairs of angles that do not determine each other's values. This topic is a component of a broader study on geometry concerning intersecting, parallel, and perpendicular lines.
