Explore 3 or 4 Circle Theorems
- Malvern College
By selecting different rules, play around with the positions of A,B,C and D and try to work out what the rule is. Try and describe it as best you can. eg For Rule 1 - check box rule 1 and check boxes Rule 2 and 3 hide objects.
1. For Rule 1 - does this rule still work for different shapes (ie when B has moved to other places)? Can you draw 3 distinct versions of this rule? 2. For Rule 2 - what happens when BC is a diameter? 3. What happens when A or D is on the other side of the circle? This is called in the alternate segment. Can you make another rule for this property?
