Check this selection of links which will bring you to the pages where I explain trigonometry to you. It is important to understand trigonometry is you want to pass your IGCSE GCSE Maths exam. Have a look at the contents page to see all my resources about trigonometry.
If you want to understand all maths questions involving Geometry and want to be able to confidently find the size of angles, construct figures, find lengths in various polygons etc, then you need to know the language. The following videos discuss all the keywords necessary for you to know to understand Maths and especially Geometry. The example maths questions will explain step by step to you for instance what a reflex angle, decagon, isosceles triangle etc is. Study the maths videos therefore carefully for your Maths revision and prepare yourself well for your Maths exam! If you don't understand Geometry, then let me know on the forum on the homepage of this site and i will help you with your maths. Good luck and have fun!
