#### A locus (in geometric terms) is a series of points that is determined by specific conditions. When we work with loci in math, it makes me feel like I am placing a pin in corkboard. We place that pin based on the instructions that are provided. In most cases, we will just moving up and down the y-axis or left and right across the x-axis. In these worksheets you will be the one placing the pin in the corkboard.

What is a locus at a fixed distance? A locus is the arrangement of all focuses which fulfill a specific condition. The locus at a fixed separation, d, from point P is a hover with the given point P as its inside and d as its span. The locus at a fixed separation, d, from a line m, is a couple of equal lines a good way off of d from line m and situated on either side of m. The locus is equidistant from two focuses. An and B is the opposite bisector of the line fragment joining the two focuses. The locus equidistant from two parallel lines, m1 and m2, is a line corresponding to both m1 and m2 and somewhere between them. These worksheets explain how to find the locus of two points at a fixed distance and write its equation.
