circle
No. A line is the locus of all points located between any two points.
triangle
Join the centre of the circle O and the point A .Extend it to both sides to form a line.This is the required locus
Another circle midway between the originals.
The locus point is the perpendicular bisector of AB. The locus point is the perpendicular bisector of AB.
The locus of a point is the set of all positions that the point can occupy where it satisfies some defining function.
The locus of a moving point so that it is equidistant from another fixed point (i.e. the distance between them is always constant) is a circle.
circle
No. A line is the locus of all points located between any two points.
The center isn't the locus, and a point on the circumference isn't the locus.The whole circumference of the circle is the locus.It's the locus of all points that have the same distance from the center of the circle.
point
A locus of points is just the set of points satisfying a given condition. The locus of points equidistant from a point is a circle, since a circle is just a set of points which are all the same distance away from the center
It is the locus of a point such that the sum of its distance from two (distinct) fixed points is a constant. So, given two fixed points, F1 and F2, an ellipse is the locus of the point P such that PF1 + PF2 is a constant. That would be an ellipsoid, a 3 dimensional thing. The 2 distances have to be measured in a fixed (2 dimensional) plane.
pitch point
A circle
The locus of all points that are a given distance from a given point of origin is a circle.To draw this, use a compass set to 2in and centered on the point of origin. Graph paper is recommended.
