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.

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 paper folding method used to find the midpoint of a line segment is called "folding in half." To do this, simply fold the paper so that the two endpoints of the line segment meet, creating a crease. The crease indicates the midpoint of the segment. This technique relies on the geometric property that folding a straight line segment in half equally divides it.

No. It is possible to fold an angle on paper to bisect it.
