What is Locus?

Locus Point: the setof all points that satisfy a given condition. A general graph of a given equation.

Two Fixed points; a line through the middle of the points. Perpendicular Bisector
One Line; two parallel lines on opposite sides of the original line
One Point; forms a circle
Two Intersecting Lines; two intersecting lines halfway between the two original lines

• The Locus of points equidistant from a single point is a set of points, equidistant from the point in every direction.
• The Locus of points equidistant from two points is the perpendicular bisector of the line segment connecting the two points.
• The Locus of points equidistant from a line are two lines, on opposite sides, equidistant and parallel to that line.
• The Locus of points equidistant from two parallel lines i another line, halfway between both lines, and parallel to each of them.

Loucs Rule:

1. 1 Point- Circle
2. 2 Points- 1 Line
3. 1 Line- 2 Lines
4. 2 Lines- 1 Line
5. 2 Intersecting- 2 other intersecting
