👉 Rectrices, also known as rectangular or rectifying lines, are a type of curve used in geometry and engineering. They are straight lines that intersect at right angles to each other, forming a shape known as a rectification. Rectrices can be defined as a special case of the more general concept of a line segment, where instead of two points, they have one point and a single line connecting it to another point. The term "rectrix" comes from Latin and means "right angle".
