Two fixed points A and B are 100mm apart Trace the complete path of a point P moving in same plane in such a way that the sum of its its distances from A and B is always equal to 125mmName the curve?

The curve traced by the point P in this scenario is an ellipse. An ellipse is a closed curve where the sum of the distances from two fixed points (foci) to any point on the curve is constant. In this case, the foci are points A and B, and the constant sum of distances is 125mm. The major axis of the ellipse is the line segment passing through the foci, and the minor axis is perpendicular to the major axis.
