Author note — to cover

Angles meeting at a full turn sum to 360 degrees, including reflex angles, several unknowns, equal-angle setups and simple algebraic angles such as 2x + 30. Require the written reason angles at a point. Straight-line and parallel-line facts are sibling pages; bearings applications sit on Mensuration. Both tiers. (G3)

• Fluency — direct questions on angles at a point, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
