👉 Antiscians, also known as "scions" or "dual-scales," are a type of conic section in which one of its two foci is at infinity. This means that if you draw an infinite line from one focus to the other, it will intersect the circle at exactly one point. In geometry, antiscians are often used to represent circles with diameters or tangents that are not perpendicular (i.e., they do not form a right angle). In particular
