Some are possible, others are not.
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.
True
Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.
Yes, it is impossible to trisect any arbitrary angle using only a compass and straightedge. This was proven in the 19th century as part of the broader study of constructible numbers and geometric constructions. While some specific angles can be trisected through these methods, the general case cannot be solved with just a compass and straightedge.
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.

Perpendicular lines that meet at right angles is one example
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.

True -
No, it is not possible to double a square using only a compass and straightedge. This problem, known as the "doubling the square" or "quadrature of the square," is equivalent to constructing a square with an area twice that of a given square. However, this requires the construction of a square root of 2, which is not constructible with these tools, as it involves a geometric construction that cannot be achieved with finite steps.
