Abstract
The constructions with ruler and compass range from the determination of points, straight lines or line segments and circles or arcs, where the ruler and compass are ideal, that is, the ruler has no measure and the compass is supposed to be closed when it is lifted from the paper. The most famous problems proposed to be solved with only ruler and compass are the well-known ones: squaring of circles, doubling of the cube and trisection of an angle. The requirement to use only ruler and compass to perform these constructions is associated with Plato’s view that the straight line and the circle were the only perfect figures (Lugo, 2022). The Greeks put all their ingenuity and effort in finding a solution to these three previous problems, but they never got there, although all that effort led to other discoveries such as: the division of a straight line segment into any number of segments of equal measure; drawing parallels to a given straight line; finding the bisector of a given angle; construction of a square of equal area to that of any given polygon.
