Grade 8 students were exploring the concept of Loci using ropes and thread in an outdoor activity in which they learn:

1. The Locus of the points at a certain distance from a given point is a circle.
2. The Locus of the points at a certain distance from a straight line is two parallel lines from both sides at the given distance.
3. The Locus of points at the same distance from two given points is the perpendicular bisector of the two given points.
