How to improve in Geometry & Mensuration

Mensuration and geometry is one of the favorite areas of examiners. Questions from this area appear in a significant proportion in the Quant section of almost all the competitive exams. If you go through the previous CAT papers, you will see around 4 – 5 questions in each of these. In order to improve in this area, firstly you should be clear about all the basic shapes and the formulas related to geometry. You should revise the formulas related to perimeter, area, surface area, volume of all the two-dimensional and three-dimensional figures as well as important theorems like mid-point theorem, proportionality theorem, Apollonius theorem and angle-bisector theorem. You are expected to know the difference between lines like median, altitude, height, perpendicular, tangent, inradius, circumradius etc. As there are plenty of figures and formulas in geometry, you must practice sufficient number of questions from this area before attempting the questions in the exam.
