Polygon types

"In geometry a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit. These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners. The interior of the polygon is sometimes called its body. An n-gon is a polygon with n sides. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions. ...
The basic geometrical notion has been adapted in various ways to suit particular purposes. Mathematicians are often concerned only with the bounding closed polygonal chain and with simple polygons which do not self-intersect, and they often define a polygon accordingly. A polygonal boundary may be allowed to intersect itself, creating star polygons. Geometrically two edges meeting at a corner are required to form an angle that is not straight (180°); otherwise, the line segments may be considered parts of a single edge; however mathematically, such corners may sometimes be allowed. These and other generalizations of polygons are described below." [Polygon. Wikipedia]

The vector stencils library "Qualifying" contains 56 qualifying symbols of radiation, polarity, phase, windings, wire, ground, connection, connector, coaxial, electret.
Use these signs to annotate or specify characteristics of objects in electrical drawings, electronic schematics, circuit diagrams, electromechanical drawings, and wiring diagrams, cabling layout diagrams.
"An electrical drawing, is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project. Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".
A complete set of working drawings for the average electrical system in large projects usually consists of:
(1) A plot plan showing the building's location and outside electrical wiring.
(2) Floor plans showing the location of electrical systems on every floor.
(3) Power-riser diagrams showing panel boards.
(4) Control wiring diagrams.
(5) Schedules and other information in combination with construction drawings.
Electrical drafters prepare wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wiring in communication centers, power plants, electrical distribution systems, and buildings." [Electrical drawing. Wikipedia]

The vector stencils library "Progressive disclosure controls" contains 12 icons of Windows 8 progressive disclosure controls.
Use it to design graphic user interface (GUI) prototypes of your software applications for Windows 8.
"With a progressive disclosure control, users can show or hide additional information including data, options, or commands. Progressive disclosure promotes simplicity by focusing on the essential, yet revealing additional detail as needed. ...
Chevrons show or hide the remaining items in completely or partially hidden content. Usually the items are shown in place, but they can also be shown in a pop-up menu. When in place, the item stays expanded until the user collapses it. ...
Arrows show a pop-up command menu. The item stays expanded until the user makes a selection or clicks anywhere.
If the arrow button is an independent control, it receives input focus and is activated with the space bar. If the arrow button has a parent control, the parent receives input focus and the arrow is activated with Alt+down arrow and Alt+up arrow keys, as with the drop-down list control. ...
Plus and minus controls expand or collapse to show container content in place when navigating through a hierarchy. The item stays expanded until the user collapses it. Although these look like buttons, their behavior is in-place.
The associated object receives input focus. The plus is activated with the right arrow key, and the minus with the left arrow key. ...
Rotating triangles show or hide additional information in place for an individual item. They are also used to expand containers. The item stays expanded until the user collapses it.
The associated object receives input focus. The collapsed (right-pointing) triangle is activated with the right arrow key, and the expanded (downward-pointing) triangle with the left arrow key. ...
Like chevrons, additional information is shown or hidden in place. The item stays expanded until the user collapses it. Unlike chevrons, the glyphs have a graphical representation of the action, typically with an arrow indicating what will happen. ... Preview arrows are best reserved for situations where a standard chevron doesn't adequately communicate the control's behavior, such as when the disclosure is complex or there is more than one type of disclosure."
