## What is the center point in a circle called?

the incenter the center of the circle that is internally tangent to all three sides of the triangle the orthocenter the intersection of the triangle’s three altitudes and. the nine-point center the center of the circle that passes through nine key points of the triangle.

## What are the parts of a circle called?

Important Circle Parts

Radius: The distance from the center of the circle to its outer rim. Chord: A line segment whose endpoints are on a circle. Diameter: A chord that passes through the center of the circle. The length of a diameter is two times the length of a radius.

## Which is correct Centre or center?

Center and centre have the same meaning. Center is the correct spelling in American English while in British English centre is correct. Notice that center (and centre) can be a noun adjective or a verb.

## What’s the minor arc of a circle?

A minor arc is the shorter arc connecting two endpoints on a circle . The measure of a minor arc is less than 180° and equal to the measure of the arc’s central angle . A major arc is the longer arc connecting two endpoints on a circle.

## How do you find the coordinates of the center of a circle?

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2 where (h k) represents the coordinates of the center of the circle and r represents the radius of the circle. If a circle is tangent to the x-axis at (3 0) this means it touches the x-axis at that point.

## What is a sector in a circle?

A circular sector also known as circle sector or disk sector (symbol: ⌔) is the portion of a disk (a closed region bounded by a circle) enclosed by two radii and an arc where the smaller area is known as the minor sector and the larger being the major sector.

## What do you call the line segment from the center of the circle to any point on the circle?

A radius of a circle is a line segment which goes from the center of a circle to a point on the circle.

## What is the outline of a circle called?

The perimeter of a circle is called the circumference although that term is used by some authors to refer to the perimeter of an arbitrary curved geometric figure.

## How do you label the area of a circle?

The area of a circle is pi times the radius squared (A = π r²).

## What are the points of a circle?

A circle is a set of all points in a plane that are all an equal distance from a single point the center. The distance from a circle’s center to a point on the circle is called the radius of the circle. A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle.

## Is the center part of the circle?

Center: The center of a circle is defined as the point in the middle of the circle. The points that make up the curve that is the circle are all equidistant from the center point.

## How do you find the parts of a circle?

The formula for the area of a circle is A = pi * r * r where r is the radius (diameter / 2).

## Is English American or British?

Whilst American English spellings are based mostly on how the word sounds when it is spoken. English was introduced to what is modern day America in the 17th century by the British settlers. Since then the language has evolved and has been influenced by the many waves of immigration to the USA.

## What is meant by minor arc?

A minor arc may refer to: an arc that is smaller than a semicircle. a term that arises in connection with the Hardy–Littlewood circle method.

## How do you name minor and major arcs?

The smaller of the two arcs is called the minor arc. The larger of the two arcs is called the major arc. In the illustrations below the circle is divided into two arcs minor arc BC and major arc BC. Minor arcs are named with the word “arc” or the words “minor arc” and two or three letters (usually two letters).

## Which arc is a major arc?

180 degrees
An arc whose measure is greater than 180 degrees is called a major arc. An arc whose measure equals 180 degrees is called a semicircle since it divides the circle in two.

## What is the general equation of a circle?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2 where ( h k ) is the center and r is the radius.

## What is an arc in a circle?

The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle it is known as a semicircular arc.
