Geometry
Geometry is a core quantitative aptitude topic covering shapes, angles, area, and volume. It is frequently asked in competitive exams and requires strong formula knowledge.
Fundamental Principles
Point
A location with no dimension.
Line
A straight path extending infinitely in both directions.
Angle
Formed when two lines meet at a point.
Polygon
A closed shape made of straight lines.
Essential Formulation Tips
- Memorize key formulas (area, perimeter, volume).
- Draw diagrams for clarity.
- Use symmetry and properties of shapes.
- Break complex shapes into simpler ones.
Shortcut Execution Techniques
- Triangle angles sum = 180°.
- Circle area = πr².
- Rectangle area = l × b.
- Use Pythagoras theorem for right triangles.

Q: How to solve geometry questions quickly?
A:
Example Breakdown: Triangle Area Example
Basic concept.Area = 1/2 × base × height.
Area = 1/2 × 10 × 5 = 25.
Final Answer: 25 cm².
Example Breakdown: Circle Area Example
Common exam question.Area = πr².
= 22/7 × 7 × 7 = 154.
Final Answer: 154 cm².
Example Breakdown: Pythagoras Example
Important concept.Use Pythagoras theorem.
c² = 3² + 4² = 9 + 16 = 25.
c = 5.
Final Answer: 5 cm.
