Congruence and proof
Designed and produced by the UK CoI
This c-book is an interactive version (plus some extras) of part of a chapter from a Japanese textbook. The chapter is about congruence and leads into proofs. It starts of with the three main congruence types. We have not included formal proofs but there are so-called ‘flowchart’ widgets that are related to it. The cbook also uses Geogebra widgets; there is an ‘introduction to Geogebra’ section for new users of Geogebra.The c-book provides:
- Feedback
- A mix of both closed and open explorations.
- Interactive diagrams
