Can I diameter be a chord?
(a) Yes, every diameter of a circle is also a chord because a chord of a circle is any line segment joining two points on the circle’s circumference.
When can you say that a chord is a diameter answer?
A segment of a straight line joining two points on a circle is called a chord; a chord that passes through the center of the circle is called a diameter.
What is the relationship between diameter and chord?
A line that joins two points on the circumference of a circle is called a chord. A chord that passes through the centre of a circle is called the diameter of the circle. A diameter divides a circle into two equal segments, each is called a semicircle. Diameter is the longest chord of a circle.
Is a chord always smaller than the diameter?
Any chord that is not a diameter of a circle will be shorter than the diameter of the circle. Any line that is tangent to a circle is perpendicular to a radius or diameter at that point, as in the figure above.
Is a chord always a radius?
A chord is sometimes a radius. 2. A diameter is always a chord.
How do you calculate chord?
Using the formula, half of the chord length should be the radius of the circle times the sine of half the angle. Multiply this result by 2. So, the length of the chord is approximately 13.1 cm.
Is every diameter of a circle also a chord?
(a) Yes , every diameter of a circle is a chord.
Can a chord be greater than the diameter?
No, the length of chord cannot be greater than the diameter of the circle as the diameter of a circle is the greatest chord of that circle.
How many chords are in a circle?
4 chords can be drawn in a circle…..)
What is chord in A circle?
The chord of a circle is defined as the line segment joining any two points on the circumference of the circle. It should be noted that the diameter is the longest chord of a circle that passes through the center of the circle.
Which is not a chord?
All diameters are chords, but not all chords are diameters. A plane is a flat surface that extends without end in all directions. A circle divides the plane into three parts: The points inside the circle, the points outside the circle and the points on the circle. 1.
Why are all chords not called diameter?
Also, the longest chord of the circle passes through its center. Hence diameter is the longest chord of the circle. AB is the diameter of the circle with center as O shown in the figure. Therefore the given statement “The longest of all chords of a circle is called a diameter.” is true.
Is a chord a radius?
Answer: As discussed above, any line segment which connects two points on the circumference of the circle is known as a chord. While a radius connects the centre of the circle with a point of a circle. Therefore, from the definition of both terms, we can state that radius is not a chord.
What is the formula for chord?
If the radius and the distance of the center of the circle to the chord are given, the chord of the circle can be calculated. We just need to apply the chord length formula: Chord length = 2√(r2-d2), where ‘r’ is the radius of the circle and ‘d’ is the perpendicular distance from the center of the circle to the chord.
Is every diameter of a circle a chord?
What is difference between chord and diameter?
The chord of a circle is a line segment joining any two points on the circle. The chord of a circle which passes through the centre of the circle is called the diameter of the circle. The diameter of a circle is the distance across a circle. The diameter is also the longest chord of a circle.
