Great-circle distance The great-circle distance or orthodromic distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior).

SYMBOLS and their M eaning CIRCLE (sacred hoop, ring): An ancient and universal symbol of unity, wholeness, infinity, the goddess, and female power. To earth-centered religions throughout history as well as to many contemporary pagans, it represents the feminine spirit or force, the cosmos or a spiritualized Mother Earth, and a sacred space.

- The circumference (from Latin circumferentia, meaning carrying around) of a closed curve or circular object is the linear distance around its edge. The circumference of a circle is of special importance in geometry and trigonometry.

Circumference of a Circle The radius of a circle is the distance from the center of a circle to any point on the circle. If you place two radii end-to-end in a circle, you would have the same length as one diameter. Thus, the diameter of a circle is twice as long as the radius.

Circle A line that goes from one point to another on the circle's circumference is called a Chord. If that line passes through the center it is called a Diameter. A line that just touches the circle as it passes by is called a Tangent. And a part of the circumference is called an Arc.

Chapter 7 Bankruptcy and Your Car Or, if you don't want to keep your car, you can surrender it in the bankruptcy. If you lease your car, your options are different -- you can continue with the lease by assuming it in the bankruptcy, or you can terminate the lease by rejecting it. If you want don't to keep your car (and the related debt) in Chapter 7 bankruptcy, you can surrender it. 2  Reaffirming a Car Loan in Chapter 7 Bankruptcy. 3  If you have a car loan, you may be able to keep your car in Chapter 7 bankruptcy by reaffirming the loan.

Diameter In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length of a diameter is also called the diameter. In this sense one speaks of the diameter rather than a diameter (which refers to the line itself), because all diameters of a circle or sphere have the same length, this being twice the radius r.

Circle Radius, Diameter and Circumference. The Radius is the distance from the center to the edge. The Diameter starts at one side of the circle, goes through the center and ends on the other side. The Circumference is the distance around the edge of the circle.ecause people have studied circles for thousands of years special names have come about. Nobody wants to say that line that starts at one side of the circle, goes through the center and ends on the other side when a word like Diameter will do.

- The circle is considered a symbol of unity, because all the regular polygons are embraced by the circle. It is also the symbol of infinity, without beginning or end, perfect, the ultimate geometric symbol.

- The circle is such a common shape that we take it for granted ... but there is more to it that just a common shape. Mathematically, the circle is defined as the set of all points that are the same distance from a given point, called the center. That distance is called the radius. The word radius comes from the Latin word for rod or spoke of a wheel, and the radii, or spokes, radiate out from the center.

- A circle is a type of line. Imagine a straight line segment that is bent around until its ends join. Then arrange that loop until it is exactly circular - that is, all points along that line are the same distance from a center point. There is a difference between a circle and a disk. A circle is a line, and so, for example, has no area - just as a line has no area. A disk however is a round portion of a plane which has a circular outline. If you draw a circle on paper and cut it out, the round piece is a disk.

circle Circle, club, coterie, set, society are terms applied to restricted social groups. A circle may be a little group; in the plural it often suggests a whole section of society interested in one mode of life, occupation, etc.: a sewing circle; a language circle; in theatrical circles.

Circumference of a Circle Thus, the circle to the right is called circle A since its center is at point A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. The distance across a circle through the center is called the diameter.

Geometry: Circles Terms. 1  Arc - Two endpoints on a circle and all of the points on the circle between those two endpoints. 2  Center - The point from which all points on a circle are equidistant. 3  Central Angle - An angle whose vertex is the center of a circle.  Chord - A segment whose endpoints are on a circle.

Circle graph In graph theory, a circle graph is the intersection graph of a set of chords of a circle. That is, it is an undirected graph whose vertices can be associated with chords of a circle such that two vertices are adjacent if and only if the corresponding chords cross each other. 1 Algorithmic complexity. 2 Chromatic number.

Equation of a Circle Definition of Circle. 1  Unlike parabolas, circles ALWAYS have X 2 and Y 2 terms. X2 + Y2=4 is a circle with a radius of 2 (since 4 =22) 2  Remember that a circle is a locus of points. A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle.

Arc (geometry) Its curved boundary of length L is a circular arc. In Euclidean geometry, an arc (symbol: ⌒) is a closed segment of a differentiable curve. A common example in the plane (a two-dimensional manifold), is a segment of a circle called a circular arc. In space, if the arc is part of a great circle (or great ellipse), it is called a great arc.
