    A locus is the set of points that satisfy a given set of conditions.
     
    Reminder: With locus problems, always draw a picture.
     
    5 Basic Loci:
     
    1.  Distance from a Point: The Circle
     
     
     
     
     
     
     
     
     
    2.  Equidistant From Two Points: Perpendicular Bisector
     
     
     
     
     
     
     
    3.  Distance from a line: Two Parallel Lines
     
     
     
     
     
     
     
     
    4.  Equidistant from Two Parallel Lines: One Parallel Line
     
     
     
     
     
     
     
     
    5. Equidistant from Intersecting Lines: The Angle Bisector
