Geometry for CAT Exam: Various Aspirants of the Geometry and Mensuration

Doorsteptutor material for CAT is prepared by world's top subject experts: get questions, notes, tests, video lectures and more- for all subjects of CAT.

  • Here one of the categorized sub-sections of the Quantitative Aptitude section is geometry and mensuration is been discussed. This the most favorite section of the exam setters and the candidates appearing in the exam. These types of exam questions are fun for the students.
  • 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, and 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, in-radius, circum-radius 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.

Below is the list of various aspirants of the geometry and mensuration that can be asked in the CAT exams:

  • Lines and Angles
  • Triangles – Basic Concepts
  • Area, Angles
  • Similar Triangles
  • Special Triangles (30 - 60 - 90,45 - 45 - 90,30 - 30,120)
  • Polygons
  • Circles

  • Solids/Mensuration – 3D Geometry
  • Co-ordinate Geometry
  • Trigonometry

Among the above topics, Co-ordinate Geometry and Trigonometry are low priority areas. If a candidate can spend even an hour on Trigonometry to understand the basic concepts and simple applications of those basic concepts – it should be enough for the CAT exam. Candidates do not need anything more than that. Similarly, as far as Co-ordinate Geometry is concerned – it is a combination of a large number of formulas. If the candidates are good at remembering stuff, 75 % of their co-ordinate geometry problems would be solved in less than a minute.
