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.
The ancient Greeks utilized a straightedge and compass to construct various geometric figures, including triangles, circles, and polygons. These tools allowed for precise constructions based on fundamental geometric principles, such as the ability to create bisectors, perpendiculars, and inscribed shapes. Notable constructions included the division of a line segment into equal parts and the construction of regular polygons, like the pentagon. However, certain problems, such as squaring the circle, were proven impossible with these tools alone.
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.

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.
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.
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.
