Where can it go? The first video on loci develops a definition and provides some quick sketches of the loci of all points with given characteristics. The presenter does an example of the loci of points a given distance from an L shape.

Closer to this point and farther from that one. Continuing with loci problems, a short video shows how to work problems that are not straightforward. The presenter works loci problems that result in a region that meets several criteria.
