Angle Reasoning Chains - Year 6

Angle Reasoning Chains helps Year 6 learners identify a geometric relationship before calculating. They combine marked adjacent parts, justify vertically opposite angles, use straight-line sums, check a full turn and explain why a tempting claim is invalid. The teaching sequence builds from a 25° + 40° crossing-line model to fresh rotated and relabelled cases.
