8.2  Loci in Two Dimensions
 
Locus of points that are of constant distance from a fixed point:
 

 
  • The locus of a point that is equidistant from a fixed point is a circle centered at that fixed point.
  • Points marked at the same distance from a fixed point \(O\) forms a circle.
  • A point that always moves at the same distance from a fixed point forms a circle.
 
Locus of points that are equidistant from two fixed points:
 

 
  • The locus of a point that is equidistant from two fixed points is the perpendicular bisector of the line connecting the two fixed points.
  • The two points of intersection are connected with a straight line.
 
Locus of points that are of constant distance from a straight line:
 

 
  • The locus of points that are of constant distance from a straight line is straight lines parallel to that straight line.
 
Locus of points that are equidistant from two parallel lines:
 

 
  • The locus of points that are equidistant from two parallel lines is a straight line parallel to and passes through the midpoints of the pair of parallel lines.
 
Locus of points that are equidistant from two intersecting lines:
 

 
  • The locus of points that are equidistant from two intersecting lines is the angle bisector of the angles formed by the intersecting lines.
