Key Topics to Revise

1

Straight Lines - Basic Concepts

  • A straight line is a curve where every point on the line segment joining any two points lies on the line
  • The equation of a straight line is a linear relation between x and y variables
  • Inclination of a line is the angle θ (0° ≤ θ < 180°) with positive x-axis measured anticlockwise
2

Equations of Straight Lines

  • Point-slope form: Most useful when slope and one point are known
  • Two-point form: Used when two points on the line are given
  • Slope-intercept form: Shows slope and y-intercept directly
3

Distance and Perpendicular Distance

  • Distance from a point to a line is the shortest distance (perpendicular distance)
  • Formula works for any line in general form Ax + By + C = 0
  • Distance between parallel lines uses the same perpendicular distance concept
4

Circles - Equations and Properties

  • Circle is the set of all points equidistant from a fixed center
  • Standard form: x² + y² = r² (center at origin)
  • Central form: (x-h)² + (y-k)² = r² (center at (h,k))
