Dynamic circle geometry
In this activity, pre-prepared learning objects allow all students to benefit from exploring dynamic circle geometry.
The dynamic circle geometry files on Geogebratube provide students with the opportunity to interact, explore, predict and confirm results in circle geometry. They will be most valuable when the classroom learning encourages group work and discussion.
It is strongly recommended that the theorems are presented in the given numbered sequence (below) and that no more than five theorems are covered in one session.
Subsequently, students will need to practise recognising the theorems in a wide variety of orientations. Provide plenty of exercises which require missing angles to be found.
Verbal explanations of the reasoning are suitable to begin with. Later, more formally written proofs will become appropriate.
