The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.

A compass and straightedge construction is a method used in geometry to create figures using only a compass and a straightedge, without the use of measurement tools. The compass is used for drawing circles and arcs, while the straightedge is utilized for drawing straight lines. This technique is foundational in classical geometry, allowing for the construction of various geometric shapes and figures, such as triangles, squares, and angles, based solely on specific geometric principles. Notably, some classical problems, like squaring the circle or doubling the cube, have been proven impossible using only these tools.
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.
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.

A construction. A construction is a geometric drawing of a figure usually made by a compass and/or a straightedge

In geometry, another word for construction is "drawing." This term refers to the process of creating geometric figures using specific tools and methods, such as a compass and straightedge, to accurately represent shapes and relationships.
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.
Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.
Constructing geometric figures means with the help of a compass, protractor and a scale with accurate measurement. Drawing may just be drawing rough figures with no accurate measurement.
In their formal geometric constructions, the Greeks did not use tools such as a ruler or measuring device for measuring lengths, as they relied solely on the compass and straightedge. These tools were used to create geometric figures through drawing and intersection methods without the need for measurement. The prohibition of any form of measurement was a fundamental aspect of their geometric approach, emphasizing pure construction over numerical precision.
Geometrical construction refers to the method of creating geometric figures using a compass, straightedge, and other basic tools without the use of measurements. It involves defining points, lines, angles, and shapes through precise, logical steps based on fundamental geometric principles. This practice is essential in studying geometry, as it helps develop spatial reasoning and a deeper understanding of geometric relationships.
