## Is a diameter always a chord?

Every diameter is a chord. This is because its endpoints lie on the circumference of the circle.

## Why is diameter the longest chord?

The diameter of a circle is considered to be the longest chord because it joins to points on the circumference of a circle. In the circle below, AB, CD, and EF are the chords of the circle. Chord CD is the diameter of the circle.

## How does chord affect lift?

If you increase the chord, lift goes up almost linearly and stability decreases, because now the wing’s lift force has a longer lever arm in flow direction. By increasing chord, you decrease aspect ratio… Lastly, this all relates to how chord length is considered during wing design.

## How do you segment a circle?

A Simple Way to Divide Circles

1. Draw line AB through the center of your circle, and divide it equally into the number of parts you want.
2. Set a compass at points A and B, scribe the two arcs as shown, and label their intersection as point C.

## What is a major sector of a circle?

A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. A sector with a central angle greater than 180° is called a major sector.

## How do you find the major sector of a circle?

In a circle with radius r and centre at O, let ∠POQ = θ (in degrees) be the angle of the sector. Then, the area of a sector of circle formula is calculated using the unitary method. Now the area of the sector for the above figure can be calculated as (1/8) (3.14×r×r).

## How many sectors are in a circle?

When two radii meet at the center of a circle to form a sector, they actually form two sectors. One of the sectors is larger than the other, unless they are both semicircles in which case they are the same size. The larger sector is called the major sector and the smaller sector is called the minor sector.

## How many minor arcs are in a circle?

Minor Arc. A chord, a central angle or an inscribed angle may divide a circle into two arcs. 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.

## How many arcs are in a circle?

A diameter of a circle divides it into two equal arcs. Each of the arcs is known as a semi-circle. So, there are two semi-circles in a full circle. The degree measure of each of the semi-circles is 180 degrees.

## What is major arc in a circle?

The major arc of a circle is an arc that subtends an angle of more than 180 degrees to the circle’s center. The major arc is greater than the semi-circle and is represented by three points on a circle.
