Konstruierbare
Konstruierbare is a term used in mathematics, specifically in Euclidean geometry, to describe a geometric object that can be constructed using only a compass and straightedge. These tools are idealized geometric instruments with specific limitations: a compass can draw circles and arcs of a given radius, and a straightedge can draw a line through two given points. The construction must be achieved through a finite sequence of operations using only these tools.
Many fundamental geometric figures are constructible. For instance, constructing an equilateral triangle given a line segment,
