Find corresponding lengths in similar shapes

Geometry and measures · Similarity (T-GEO-019)

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: Corresponding sides and scale factors
Fluency: Lengths in similar triangles and polygons
Reasoning: Explain which dimensions scale linearly, quadratically or cubically.
Application: Find an inaccessible height from similar triangles
Common misconception: Length, area and volume scale factors differ.

Video brief

Model how to find corresponding lengths in similar shapes. Explain each step; pause for a matching shadow question.
