Parts of Circles Diameter is one of the terminologies that we use for circle. Diameter of circle is defined as a line that passes from center and touches two points on boundary of circle. Often the word diameter is used to refer line itself. Diameter is twice of radius and is also called as Chord.f we join the two radius, which moves in the opposite direction from the center of the circle is called the Diameter of the circle, which is a part of a circle. We observe that two radius join to form a diameter, so we say that the diameter = radius * 2. Now we talk about another term related to the circle i.e. chord.

Arc Of A Circle Definition of Arc of a Circle. The arc of a circle is a portion of the circumference of a circle. Measure an arc by two methods: 1) the measure of the central angle or 2) the length of the arc itself. Measure of the central angle: The XZ arc measures 120°.

Circle graph A graph is a circle graph if and only if it is the overlap graph of a set of intervals on a line. This is a graph in which the vertices correspond to the intervals, and two vertices are connected by an edge if the two intervals overlap, with neither containing the other.

- Introduction: A circle is all points equidistant from one point called the center of the circle. Segments drawn within, through, or tangent to the circle create angles which we can define and measure. Important facts: The measure of a central angle is the same as the measure of the intercepted arc.

Circle Equations Circle Equations. A circle is easy to make: Draw a curve that is radius away from a central point. And so: All points are the same distance. from the center. In fact the definition of a circle is. Circle: The set of all points on a plane that are a fixed distance from a center. Let us put that center at (a,b) . So the circle is all the points (x,y) that are r away from the center (a,b) .

Circle The centre of a circle is the point in the very middle. The radius of a circle is a line from the centre of the circle to a point on the side. All points on the edge of the circle are at the same distance from the centre. In other words, the radius is the same length all the way around the circle. Mathematicians use the letter r for the length of a circle's radius.

- The circle is a highly symmetric shape: every line through the centre forms a line of reflection symmetry and it has rotational symmetry around the centre for every angle. Its symmetry group is the orthogonal group O(2,R). The group of rotations alone is the circle group T. All circles are similar. A circle's circumference and radius are proportional.

Circle of latitude A circle of latitude on Earth is an abstract east–west circle connecting all locations around Earth (ignoring elevation) at a given latitude. Circles of latitude are often called parallels because they are parallel to each other; that is, any two circles are always the same distance apart.

Circumscribed circleupdate In geometry, the circumscribed circle or circumcircle of a polygon is a circle which passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. A polygon which has a circumscribed circle is called a cyclic polygon (sometimes a concyclic polygon, because the vertices are concyclic). All regular simple polygons, all triangles and all rectangles are cyclic.

Definitions &Translations 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.

Circle Variations on the circle include the Brandt Circle, invented by an art teacher at Hoople University of Northern South Dakota. This shape consists of an oval, with squiggly parts on the X axis. He invented the Brandt Sphere two years later, which the New York Times described as a rotten tomato gone...rotten..

radius diameter - the length of a straight line passing through the center of a circle and connecting two points on the circumference. 2. diameter - a straight line connecting the center of a circle with two points on its perimeter (or the center of a sphere with two points on its surface) straight line - a line traced by a point traveling in a constant direction; a line of zero curvature; the shortest distance between two points is a straight line.
