Topics in Coordinate Geometry
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
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
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
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))
