Coordinate Geometry Practice & Questions
Bridges algebra and geometry on the Cartesian plane, focusing on linear equations, parallel/perpendicular lines, and intersections.
Core Concepts in Coordinate Geometry
Questions from this topic consistently evaluate the following core principles across SSC, Railways, and Banking papers:
- Distance and section (internal/external) formulas
- Slope of parallel (m1=m2) and perpendicular (m1*m2=-1) lines
- Intercept form of a line (x/a + y/b = 1)
- Centroid and area of a polygon
Exam Speed Strategy & Shortcuts
- Perpendicular lines have slopes that multiply to -1.
- Use the shoelace method for fast computation of triangle areas.
