Geometry, Coordinate Geometry and Menstruation are grouped
together since they deal with the portion of QA that can be visualized. Of the
three, maximum weightage is given to geometry, although every CAT paper will have 3-4 questions on mensuration, as well as a couple of
questions on coordinate geometry, totaling about 25-30% of questions in the QA
section.
Topics that need to be covered in geometry are basic
theorems involving triangles, circles and parallel lines. A common type of
question that is often asked in CAT is to find the value of certain angles or
length of certain sides. Therefore, make sure that you cover topics such as
congruency and similarity of triangles.
The only things that you need to do in coordinate geometry
are straight lines and circles. Given the equation of a circle, you should be
able to comment on the centre and radius of the circle and draw it on a piece
of graph paper, and nothing more. Similarly, you should know what the slope and
y-intercept of a given straight line equation is, and be able to draw the line
on a piece of graph paper.
For mensuration, flip through a school level textbook
for basic formulae on areas, surface areas and volumes of triangles, circles,
cylinders, cones, cuboids and spheres. Mensuration problems are
calculation intensive, and require lots of practice.
