Pairs of angles
Pairs of Angles introduces Class 9 Mathematics learners to how two angles are related when they share a vertex, a common arm, or a position formed by intersecting lines. Within the Lines and Angles chapter, students identify complementary and supplementary angles, adjacent angles, and linear pairs, then use their properties to calculate unknown measures. The topic also builds the foundation for recognising vertically opposite angles and applying angle relationships in diagrams and everyday geometric situations.
