loci and regions

not too sure why this topic remains on the syllabus?
it harks back to a Euclidean tradition I guess
the tasks at sciencevsmagic are interesting and challenging, if you have IT availability

the best powerpoint is Dan Walker's
I've adjusted it but this is his (admirable) work

a powerpoint showing the constructions (click and leave, needs clicking between slides)

a loop to remind students of the loci they need to know (which could be played whilst they work: click and leave)

the questions

the mrreddy.com geometry toolbox can be helpful, available in the 'teachers' section of Bruno Reddy's site

















alternative construction for the angle bisector




these are questions from the KS3 SAT papers
