Top 3 Videos on Triangles for CAT Quantitative Aptitude by PW

Triangles can be tricky in CAT Quantitative Aptitude when you have to remember different properties, calculate areas, identify triangle centres, and solve diagram-based questions quickly. You may know the formulas but still struggle to decide which method to apply. 

These 3 Physics Wallah videos help you revise triangle basics, understand important centres and lines, practise area-based questions, and learn shortcuts for right-angled triangles. Each lesson focuses on a different part of geometry, helping you strengthen concepts and improve problem-solving accuracy. 

Use these videos alongside the CAT Quantitative Aptitude Syllabus to guide your revision.

Video 1: Understand Triangle Centres and Lines Through CAT Practice

This video explains important triangle centres and lines, including medians, the centroid, angle bisectors, the incenter, perpendicular bisectors, the circumcenter, and the orthocenter. You will also revise equilateral and right-angled triangle properties, circle-related concepts, triangle areas, and Pythagorean triplets. 

Practice questions, including CAT previous-year questions, help you connect these concepts with exam-style problems. Watch this lesson if you need help identifying triangle centres or remembering their properties. It can also help you improve diagram reading and revise related geometry concepts before attempting timed CAT Quantitative Aptitude practice.

Video 2: Master Basic Triangle Properties and Pythagoras Theorem

This video builds your foundation in triangle geometry by explaining different triangle types and their basic properties. You will practise applying these concepts through questions and then revise the Pythagoras Theorem and useful Pythagorean triplets with examples. The step-by-step approach helps you understand how triangle properties work in numerical problems instead of relying only on memorised formulas. 

Start with this lesson if your geometry basics need revision before you move to advanced questions. It can help you recognise relevant properties, choose suitable methods, and solve fundamental CAT Quantitative Aptitude questions more accurately.

Video 3: Solve Triangle Area Questions Using Heron’s Formula and PYQs

This video focuses on triangle areas and their application in CAT Quantitative Aptitude. You will revise the area of a triangle, Heron’s Formula, and important properties of equilateral and right-angled triangles. The lesson also covers the Pythagoras Theorem, Pythagorean triplets, practice questions, and CAT previous-year questions. These examples help you understand how different geometry concepts can work together in an exam problem.

Watch this video after revising basic triangle properties, especially if you find area-based questions difficult. Practising the examples can help you improve calculation accuracy and apply the right formula confidently.

How to Prepare Triangles Topic for CAT Exam?

Preparing Triangles for CAT 2026 requires understanding properties, area formulas, triangle centres, and right-angle shortcuts. Practise CAT-level questions regularly to improve speed, accuracy, and confidence. 

• Revise the basics first: Learn triangle types, properties, and the Pythagoras Theorem before attempting advanced problems.

• Remember important centres: Revise the centroid, incenter, circumcenter, and orthocenter along with their defining properties.

• Practise area questions: Apply triangle area formulas and Heron’s Formula to different question types.

• Learn useful shortcuts: Recognise common Pythagorean triplets and practise right-angled triangle problems.

• Solve timed questions: Use mixed geometry practice to improve accuracy, question selection, and speed.

For a broader preparation plan, refer to PW’s MBA Quantitative Aptitude guide, which covers major Quant topics and preparation methods. You can also use the 100 Days Plan for CAT to organise revision and practice during the final preparation phase.

These 3 PW videos take you from basic triangle properties to important centres, area-based questions, right-angle shortcuts, and mixed geometry practice. 

Watch the lessons according to your preparation level, solve the questions yourself, and revisit concepts you find difficult. Consistent revision and timed practice can help you improve accuracy, strengthen geometry fundamentals, and approach CAT 2026 Quantitative Aptitude questions with greater confidence.
