angels1 Posted March 3, 2013 Report Share Posted March 3, 2013 Hey guys! I'm doing the 2013 Circles Math IA and I got a 17 on my last IA. to get a 7, in this course, I need to get atleast a 15 on this one.I am using similar triangles to solve this IA, my teacher said if my introduction isnt good, my overall math Ia mark will be low. Therefore, can someone please post up a very good explanation why similar triangles can be used? THerefore, I can use it to judge my introduction to see what I need to include or take out?Thanks!Please reply ASAP! Reply Link to post Share on other sites More sharing options...
Mc837 Posted March 3, 2013 Report Share Posted March 3, 2013 I basically copy what the IA says as my introduction, then in the body I explain why I used the method I did.I did the same portfolio and got 95%. Anyway, if you look in your maths sl/hl guide you should find assessment criteria at the end. If you need the syllabi you can find them here.Hope this helped!
