 Concepts of Geometry
An arc of a circle is measured in degrees, according to the angle formed by joining its two ends to the center of that circle.
When applied to transformational geometry, the determinant of a 2 × 2 matrix signifies the ratio of the area of the transformed shape to the original and its sign (plus or minus) denotes whether the image is direct (the same way round) or indirect (a mirror image).
in geometry, a curve formed by cutting a right circular cone with a plane so that the angle between the plane and the base is greater than the angle between the base and the side of the cone.

Arcs are the wires in a technology, and they are constructed from pieces of geometry on the layers.
For example, a p-device arc will have an N-well, or N substrate under it, and a p-type diffusion will end up as part of the drain or source of the P transistor to which it is connected.
The length of the arc is not important, but the smaller dimension is presumed to be the width and defines the default for this arc type.

 Deprojection
In the TAN (tangent) or gnomic geometry, the projection of a point of the celestial sphere onto the plane is found by extending the line from the center of the sphere to the point on the tangent plane.
In the SIN (sine) or orthographic geometry, common in radio aperture synthesis, the projection point is on the perpendicular between the point on the sphere and the surface of the tangent plane.
In the ARC geometry, the projection point is on an arc passing through the point on the sphere and the tangent plane, with the center of the arc at the reference point.

Mirrored 3 point arcs are then connected through the centerline with the arc tangent to the arch line.
The middle section of the arcs (which will be used in the final instrument arch) are determined for the top plate by using the golden division of 1/2 the arc (centerline to edge), hile the back arcs use the golden division ^2of the arc.
So the arcs formed crossways on the upper bout are fuller than the arcs on the lower bout.

 Geometry of Solar Eclipses
A direct consequence of this fortuitous geometry is that during a total solar eclipse, the Moon occults the Sun with a nearly perfect fit.
Eclipse geometry is complicated by the fact that Earth's orbit around the Sun is elliptical.

Geodesic line), and for this reason their role in spherical geometry is the same as the role of straight lines in planimetry.
However, whereas any segment of a straight line is the shortest curve between its ends, an arc of a great circle on a sphere is only the shortest curve when it is shorter than the complementary arc.
Spherical geometry differs from planimetry in many other senses; for example, there are no parallel geodesic lines: two great circles always intersect, and, moreover, they intersect in two points.

The eastern arc, oriented sub-parallel to relative motion, is dominated by transcurrent tectonism.
Variations in the level and depth of seismic activity along the western arc suggest that the northwestern section of the arc represents a subduction boundary, whereas the southeastern section represents a collision boundary.
The Hellenic Arc is subjected mainly to subduction, whereas the shorter Cyprian Arc is subjected to subduction, collision and transcurrent tectonic processes.

 YetiFan Forum. - Arc with 100mm forks - @ www.aimoo.com
The ARC's from 1999 to 2003 were damn strong.....not sure a 2004 Scandium ARC would handle a Boxxer...not that it is meant to of course...
A 100mm fork is a fine fit for the ARC most people just prefer the 80mm running 20mm does not adversely affect the geometry either.
Arc's are pretty standard 71 and 73 (presumably on 80mm forks at 20mm sag), so 20mm extraswill get close to 70 and 72 and change the 'perfect race geometry'.

The arc was modelled as a rectangular current sheet, composed of a mix of threadlike current segments and with a current density varying across the propagation direction.
We found the magnetic induction of the arc is a convolution product of the current density, and a function depending on the breaker geometry and arc model.
Notably, position, arc size, and electric conductivity could all be determined, and then used to characterize the arc mode, diffuse or concentrated, and study the condition of its mode changing.

 Conjectures in Geometry: Arc Length   (Site not responding. Last check: 2007-09-22)
The arc length of a circle is the distance from one point on the circumference to another point on the circumference, "traveling" along the edge of the circle.
Because we know that the measure of the central angle is equal to the arc it intercepts, (Inscribed angle conjectures) by dividing that measure by 360 degrees, we find out what fraction of the circumference that the arc covers.

 Arc | English | Dictionary & Translation by Babylon
ARC is a file format by SEA (System Enhancement Associates) that was very popular before Phil Katz's introduction of the ZIP format.
The ARC program essentially made obsolete the use of combinations of the SQ program to compress files and the LU program to create.LBR archives by combining the functions of both compression and archiving into a single program.
The.arc format was the subject of quite a bit of controversy in the 1980s - an important event in the open source debate.

 Question Corner -- Counting Obtuse Triangles in an Inscribed Polygon
First of all, there's a theorem in geometry which says that angle ABC is half the measure of the "other" arc from A to C (the one not containing B).
Therefore, angle ABC is obtuse if and only if the other arc is more than 180 degrees, which is true if and only if the arc from A to C through B is less than 180 degrees (less than a semicircle).
This shows that if the arc is less than a semicircle the angle ia obtuse; you can draw similar pictures which show that, if the arc is more than a semicircle, the angle is acute.
