Presumed Knowledge
You are not required to be familiar with all of the topics listed in the presumed knowledge section of the IB math program, as some will be covered as part of the core. However, by the exam you will need to make
sure you understand all of the things listed.
This page is for you to use to ensure you have all the necessary presumed knowledge before the final exam.
Work through the page carefully and ask your teacher about any areas you are unsure of.
There are many references to BBC Bitesize Revision: GCSE math
and BBC Bitesize Revision KS3 math
You are strongly advised to use this link and work through the sections
given and do any activities suggested and the "testbites". It will help a lot.
Much of the information in this chapter will be covered in the core of the IB
MS course, but it is important that you also do work of your own, to reinforce the concepts covered in class.
The BBC site used is extremely useful for the IB MS course and you will find
it useful for revision, it also has links to other good math sites
Presumed Knowledge : Geometry and Trigonometry
Point : A precise location or place on a plane. Usually represented by a dot. A point shows an exact position or location on a plane surface. ...
Go to
A line : is a straight onedimensional figure having no thickness and extending infinitely in both directions.
Plane : A surface containing all the straight lines that connect any two points on it.
Angle : A pair of lines sharing a common endpoint (vertex)
Acute < 90°
Obtuse >90°
(x , y) coordinate plane
Go to
for a detailed explanation, but basically its where you have two axis x and y and you plot ordered pairs, coordinates.
Simple two dimensional shapes and their properties, including perimeters and areas of circles, triangles quadrilaterals and compound shapes
Sine, cosine and tangent of acute angles. (more will be done in the MS core)
Pythagoras' theorem
Go to BBC Bitesize revision GCSE math
Go to section Shape and space (foundation and intermediate) and go through the sections, angles, area and circles.
Go to shape and space (intermediate and higher) and go through the sections, area + volume, Pythagoras and trigonometry.
Go to BBC Bitesize revision KS3 math shape and space
and the sheet on properties of quadrilaterals is very useful
