👉 The term "sesquiduple" is a mathematical concept used in algebraic geometry. It can be defined as a pair of lines that intersect at one point, and it's named after the Greek word for "pair." This pair of lines could potentially represent a geometric shape such as an ellipse or a hyperbola. In algebraic geometry, a sesquiduple is a line in two-dimensional space which intersects with another line at exactly one point. It is usually represented by an equation
