👉 The term "arcocentrum" is a Latin term that refers to a circle or ellipse that passes through the center of a given point on a plane. It can be thought of as the point at which two lines meet, and it is often used in geometric constructions such as constructing triangles from intersecting circles (which are commonly known as "arcocentrials"). This term is also found in various mathematical contexts, particularly in the study of geometry and trigonometry.
