This math topic focuses on calculating the complementary angles that sum up to 180 degrees. Each question presents a scenario where one angle is given, and the task is to determine the degrees of the other angle so that together they form a straight angle (180 degrees). This practice is part of a larger unit on geometry, specifically dealing with intersecting, parallel, and perpendicular lines. Understanding how to find complementary angles is essential in solving problems related to these geometric concepts.
