Tips and Tricks for Geometry & Mensuration for GATE ECE 

Before you learn the tricks, ensure that you have read the Geometry & Mensuration GATE ECE notes thoroughly. After that, you can keep these tips in mind while solving the questions.

  • The most important tip is to learn the formulas by heart. Write all the formulae several times if you can.
  • Make sure that while solving the Geometry & Mensuration GATE ECE questions and answers pdf, you write down every formula so that it helps you remember it.
  • Whenever you get an asymmetrical shape, try to divide it into different symmetrical figures and form right-angled figures.
  • Remember that a square and rectangle's diagonals are equal and bisect each other at a 90-degree angle.
  • Learn the divisibility rules for 7 and 11. For the Geometry & Mensuration online test, where you have to find out the volume or perimeter of a specific figure, you can check whether any of the options is divisible by 11 or 7 because the value of π is 22/7. So if any of one of the options is divisible by these numbers, then the answer will be that number. However, if more than two options are divisible by the numbers, you should solve it by applying the formula.
  • Lastly, practice Geometry & Mensuration online quiz as much as you can and read the questions carefully while solving.
