How to improve in Geometry & Mensuration

If Geometry & Mensuration is your weak area, here is a comprehensive collection of the exact material you need to make it your strong area.


Mensuration and geometry is one of the favorite area 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 examinations you will see around 4 – 5 questions in each of the years. In order to improve in this area, firstly you should be clear about all the basic shapes and the formulas related to the same. You should revise the formulas related to perimeter, area, surface area, volume of all the two-dimensional and three-dimensional figures as well. Do revise the important theorems in Geometry like mid-point theorem, proportionality theorem, Apollonius theorem and angle-bisector theorem. Do understand 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.

Geometry - Polygons
Area enclosed under region.
Geometry - Wastage is not always a waste
Bring in Focus – PYTHAGORUS
Similar or Dissimilar
Geometry – Angle Bisector Theorem
Geometry-Application of Similarity SJ – HS
Net Percentage change in Volume, Geometry or Percentage
Tangents and Chords ; These are not Lords
