Abstract

Proving is an essential activity in maths. This requires a useful conjecture and, especially in school maths, conclusions that are also ‘convincing’. For these three activities, there are references to diagrammatic thinking according to Peirce. Thales' theorem is used to illustrate how the modification of diagrammatic systems influences proof techniques and the associated skills and creativity required.
