Identify a pattern. A locus is a set of points satisfying a certain condition. Try to find out the locus of P. You can use test point P1 to help you to find the locus. What is the locus of points at a given line? This contradicts the uniqueness of the points. Notice the formation of the isosceles triangles, where the congruent (equal) sides represent the distances to each friend. In this case (-a, 0) is the focus, x = a is the directrix, the vertex is at (0,0). This indicates the point can be dragged with a mouse. A Circle can be defined as the set of points in a plane that are equidistant from a fixed point in the plane surface which is known as the centre. (The phrase "locus of points for a circle" does not seem to be conventionally defined.) In other words, a circle can be described as the locus of a point moving in a plane, in such a way that its distance from a fixed point is always constant. Locus around a point. The point is called the focus, and the line is called the directrix. A circle is the locus of all points equidistant from a fixed point known as its centre. Locus Theorem 1: The locus of points at a fixed distance, d, from the point, P is a circle with the given point P as its center and d as its radius.
