A geometrical construction
One possible answer is: a point.

Drawing is creating a figure without tools (i.e. a ruler, a compass, etc.) Constructing is creating a figure with tools.
In constructing a geometric figure, items such as a ruler or a compass are typically allowed, while items like a calculator or digital tools are not permitted. The focus is on using traditional tools that facilitate precise drawing and measurement without relying on technology. Additionally, any item that imposes a specific measurement or fixed angle, like a protractor, might also be restricted depending on the guidelines of the construction task.

In constructing a geometric figure, commonly allowed items include a straightedge or ruler for drawing straight lines, a compass for creating circles and arcs, and a protractor for measuring angles. Additionally, pencil and paper are essential for making marks and keeping a record of the construction. Some constructions may also utilize tools like graph paper or software for digital representations.
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.

Usually a pair of compasses, a protractor and a straight edge such as a ruler.
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.
