Geometry and measures · Angles (T-GEO-003)

v1 mapping, pending teacher review. Only AQA and Edexcel are mapped so far. The first 3 pilot worksheets and their worked answers are available; remaining worksheets are coming soon. All videos are still coming soon.

Retrieval: Triangle decomposition and full turns
Fluency: Regular and irregular polygons
Reasoning: Give a reason for each angle step.
Application: Find the number of sides and justify it
Common misconception: Angles that look equal still need a mathematical reason.

Video brief

Model how to calculate interior and exterior polygon angles. Explain each step; pause for a matching shadow question.
