a straight line and a circle
False, other geometric objects exist which can be defined as a parrticular locus of points, such as the parabola and the hyperbola.
A drafting tracer is a tool used in technical drawing and drafting to create precise lines and outlines. It typically consists of a thin, flexible arm that can be adjusted to various angles, allowing for accurate reproduction of shapes and designs. Tracers are often used in conjunction with templates or other drawing aids to enhance the efficiency and accuracy of the drafting process. They are particularly useful for creating complex geometric figures and ensuring consistency in line work.
Drafting is done on a drafting table, with the help of a T-square, a compass, and other such devices.
In constructing a geometric figure, a straightedge or ruler is typically allowed for drawing straight lines, while a compass is used for creating arcs and circles. These tools enable precise constructions based on geometric principles. Other items, such as pencils and erasers, are also commonly used for drafting and refining the figure. However, measurements and calculations using a protractor or measuring tools are generally not permitted in classical geometric constructions.
Not sure. The answer is not "a set" since a set can also refer to collections of abstract concepts (not objects), they can be empty (collections of no objects), the elements of a set need not have anything in common.
The simplest lever can be constructed with a ruler and an eraser. Place the ruler on top of the eraser and you have a lever. Many other objects can perform the same function
An ellipsoid or a toroid or other 3-dimensional objects with more than one "holes". Or simply a ... sphere.
AutoCAD does not support parabolas. You would need to download an AutoLISP routine or approximate the parabola with it's geometric equation and a spline. The downside to an AutoLISP routine is that you do not know how good it is and it might not play nice with other commands.
A "carpenter" is a skilled craftsperson who performed carpentry. Carpenters work with wood to construct, install and maintain buildings, funiture and other objects. -Wikipedia-
A triangular ruler, often called a triangle or set square, is a geometric tool used in drafting and drawing. It typically features a right angle and two other angles, allowing for precise measurement and drawing of straight lines, angles, and geometric shapes. Commonly made of plastic or wood, it is used by architects, engineers, and artists to ensure accuracy in their work.
You construct a Hexagon by drawing 8 lines that touch each other.
One can get second-hand drafting tables on Amazon and E-bay for cheap. Other websites which offer great quality drafting tables are Wayfair and Hayneedle.
