Ancient mathematicians primarily used simple tools such as the straightedge and compass for geometric constructions. The straightedge was used for drawing straight lines, while the compass was employed to draw circles and arcs with a fixed radius. These tools allowed mathematicians to create various geometric figures and explore properties of shapes, leading to significant advancements in geometry. Additionally, some cultures utilized other implements like the ruler or marked sticks for more precise measurements.
When performing geometric constructions, the essential tools are a compass, a straightedge (ruler without markings), and a pencil. The compass is used to draw circles and arcs, while the straightedge helps create straight lines between points. These tools allow for precise constructions based on classical geometric principles without relying on measurements. Additionally, paper is needed to carry out the constructions.
Geometric constructions with paper folding, also known as origami, involve creating shapes and figures using folds rather than cuts. These constructions can achieve various geometric tasks, such as bisecting angles, constructing perpendicular lines, and creating polygons. Notably, origami can also be used to solve complex problems, like constructing the square root of a number or creating geometric figures that are otherwise challenging with traditional tools. The principles of origami have applications in mathematics, art, and even engineering.
The Greeks, using only a compass and straightedge, could construct regular polygons and circles due to their ability to create precise geometric figures based on certain mathematical principles. However, some constructions, like trisecting an arbitrary angle or duplicating a cube, were proven impossible within these constraints, as they required the solution of cubic equations or other geometric constructs unattainable with just those tools. This limitation revealed the boundaries of classical geometric constructions and led to deeper explorations in mathematics. Ultimately, these challenges contributed to the development of modern algebra and geometry.

The impossibility of trisecting an arbitrary angle using only a compass and straightedge is a result of the limitations imposed by classical geometric constructions. This conclusion is rooted in the field of abstract algebra, specifically the properties of constructible numbers and the fact that the angle trisection leads to solving cubic equations, which cannot be accomplished with just these tools. While certain specific angles can be trisected, there is no general method for all angles. This was proven in the 19th century as part of the broader exploration of geometric constructions.

It enabled geometric information to be converted into algebraic form. This meant that the tools of algebra could be applied to solve geometric problems and the tools of geometry to algebraic problems. That greatly increased the ability of mathematicians to solve problems.

Squaring the circle, duplicating the cube, and trisecting an angle were constructions that were never accomplished by the Greeks with only a straightedge and compass. These are known as the three classical geometric problems that cannot be solved using only those tools.
