## Can two chords be parallel in a circle?

Complete step-by-step answer: It can be seen that the equal chords may be either parallel to each other or they may be intersecting as well. Therefore, the statement of the question “Two equal chords of a circle are ALWAYS parallel.” is definitely False, because it is possible for two equal chords to intersect as well.

**How do you find the distance between two parallel chords in a circle?**

A chord of length 10 cm on a circle of radius 6 cm forms two right triangles with a hypotenuse of 6 cm, an opposite side of 5 cm, and an adjacent side = sqrt (11) cm. So, the mid-point of each chord is sqrt(11) from the center of the circle. Therefore, the two parallel chords are 2*sqrt(11) cm apart.

### How do you find the length of a chord in a circle?

r is the radius of the circle. c is the angle subtended at the center by the chord….Chord Length Formula.

Formula to Calculate Length of a Chord | |
---|---|

Chord Length Using Perpendicular Distance from the Center | Chord Length = 2 × √(r2 − d2) |

Chord Length Using Trigonometry | Chord Length = 2 × r × sin(c/2) |

**What is the distance between two parallel chords of length 32 and 24?**

Hence, the distance between two parallel chords of lengths 24 cm and 32 cm if radius of the circle is 20 cm is 28 cm or 4 cm.

#### What happens when two chords are parallel?

The measures of the arcs between parallel chords of a circle are equal. Similarly, if the measures of the two arcs between two distinct chords are equal, then the chords are parallel. If two chords are equal in length, then the arcs between the endpoints of each chord will be equal in measure.

**What are parallel chords?**

A sequence of chords consisting of intervals that do not change as the chord moves.

## How do you find the radius of two chords?

Answer: The radius of a circle with a chord is r=√(l2+4h2) / 2, where ‘l’ is the length of the chord and ‘h’ is the perpendicular distance from the center of the circle to the chord.

**How do you find a chord?**

For every note in the scale, there is a chord that starts on that note. The way to figure out what chords are in a key is to look at each note in the key and use a pattern to figure out each chord. The first note, C, gives us the C Major chord. The second note, D, gives us the D minor chord.

### What is the distance in cm between two parallel chords of lengths 30 cm and 48 cm in a circle of radius 25 cm?

Answer: If the chords are on the same side of the diameter, then distance between them is 5cm.

**How do you use parallel chords?**

The usual parallel chord in a major key is a minor third below the root and the counter parallel is a major third above. In a minor key the intervals are reversed: the tonic parallel (e.g. Eb in Cm) is a minor third above, and the counter parallel (e.g. Ab in Cm) is a major third below.

#### What is parallel music?

In music, a major scale and a minor scale that have the same tonic are called parallel keys and are said to be in a parallel relationship. The parallel minor or tonic minor of a particular major key is the minor key based on the same tonic; similarly the parallel major has the same tonic as the minor key.

**What is chord in a circle?**

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. The infinite line extension of a chord is a secant line, or just secant. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse.

## What is the length of the chord?

There are two basic formulas to find the length of the chord of a circle: Chord length using perpendicular distance from the center = 2 × √(r2 − d2). Let us see the proof and derivation of this formula. In the circle given below, radius ‘r’ is the hypotenuse of the triangle that is formed.
