This worksheet focuses on finding complementary and supplementary angles in various scenarios. Students will calculate the complement and supplement for given angle measures, identify right angles, and name complementary angles in different configurations. The assignment also includes solving for unknown angles using algebraic expressions and working with diagrams to identify congruency in supplementary angle pairs. This comprehensive geometry exercise enhances critical thinking and reinforces angle relationships in Euclidean space.
