👉 The term "monitrix" in mathematics refers to a geometric representation of a circle. It is used to show the size or scale factor between two points on a given line segment, as in a compass and straightedge drawing. The monitrix measures the ratio of the distance from one point on the line segment to another point along that line segment. For example, consider a circle with radius 5 units, which is shown by a monitrix of size 2 (since its length
