Angles - Remainder of 180 Degree Angle (Level 3)

This math topic focuses on understanding and computing the complementary angles that sum up to 180 degrees. It is specifically tailored towards working with various angle pairs, exploring how different angles combine to make a straight angle (180°). Each problem presents one angle, and the task is to find its complement to reach 180 degrees. It is structured to enhance proficiency in basic geometry concepts, specifically dealing with intersecting, parallel, and perpendicular lines through practical angle calculations.
