Length of chord formula class 10

The chord of any circle is an important term.

The chord of a circle can be stated as a line segment joining two points on the circumference of the circle. The diameter is the longest chord of the circle which passes through the center of the circle. The figure shown below represents the circle and its chord. In the circle above with center O, AB represents the diameter of the circle longest chord of a circle , OE represents the radius of a circle and CD represents the chord of a circle. Let us consider CD as the chord of a circle and points P and Q lying anywhere on the circumference of the circle.

Chord of a circle is a line segment that links two locations on the circumference of the circle. A circle is a two-dimensional shape where a set of all points are equally spaced from a fixed point in a plane. The fixed point is termed the center of the circle. Diameter of the circle is a line that meets 2 points on the edge of the circle and goes through the center and distance surrounding the circle is termed circumference. Thus we can understand that the diameter is the longest chord of a circle that crosses through the center of the circle. Chord of a circle can be defined as the line segment connecting any two points on the circumference of a circle. Here OE denotes the radius of the circle. AB is both the diameter as well as the chord in the diagram. This implies the diameter of the circle is the longest chord. Chords that are equal distances from the center of a circle are recognized as equal chords. However, the chords that are not at equal distance from the center of a circle are supposed to be unequal chords.

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. A line segment that joins two points on the circumference of the circle is defined as the chord of the circle. Among the other line segments that can be drawn in a circle, the chord is one whose endpoints lie on the circumference. Observe the following circle to identify the chord PQ. Diameter is also considered to be a chord which passes through the center of the circle.

The chord of a circle can be 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 which passes through the center of the circle. The figure below depicts a circle and its chord. Let us consider the chord CD of the circle and two points P and Q anywhere on the circumference of the circle except the chord as shown in the figure below. Question: Find the length of the chord of a circle where the radius is 7 cm and perpendicular distance from the chord to the center is 4 cm.

The radius of is feet and. Find the length of chord. We begin by drawing in three radii: one to , one to , and one perpendicular to with endpoint on our circle. We must also recall that our central angle has a measure equal to its intercepted arc. Our perpendicular radius actually divides into two congruent triangles. Therefore, it also bisects our central angle, meaning that. Therefore, each of these triangles is a triangle, meaning that each half of our chord is simply half the length of the hypotenuse our radius which is 6. Therefore, each half is 3, and the entire chord is 6 feet. If a chord is units away from the center of a circle, and the radius is , what is the length of that chord?

This article will explain the chord length formula with examples. Like Article. Thus we can understand that the diameter is the longest chord of a circle that crosses through the center of the circle. Chord of a circle is a line segment that links two locations on the circumference of the circle. Solution: We know that the radius of a circle is always perpendicular to the chord of a circle and it acts as a perpendicular bisector. Tangents will always be perpendicular to the radius of the given circle. Two chords are identical in length if they are at an equal distance from the center of a circle. A Sector of a Circle: The sector of a circle is the area enclosed by 2 radii and the corresponding arc. Become a problem-solving champ using logic, not rules. More Articles for Maths. If the angles subtended by chords in a circle are equal in the measurement, then the length of the chords is equal. In other words, the chord is a line segment whose both ends lie on the circumference of a circle. The radius of a circle is the distance from the center to any point on the circumference. Calculate the length of the chord where the radius of the circle is 7cm and the perpendicular distance drawn from the center of the circle to its chord is 4 cm. This is the converse of the first theorem.

The chord of any circle is an important term.

Multiplication Tables. What is Chord of a Circle? In fact, the diameter is the longest chord to the circle. It says that chords at an equal distance from the center of a circle are equal in measure. We may also calculate the chord length if we know both the radius and the length of the right bisector. A circle can have various chords and the largest chord of a circle is the diameter of the circle. Last updated on May 3, Our Team. Learn about Secant of a Circle Relationship Between Radius and Chord of a Circle Radius of a circle is defined as any line segment that joins the center of the circle to any location on the circle. However, the chord of a circle is a line segment connecting any two points on the circumference of the circle. You will be notified via email once the article is available for improvement. Consider the above figure where r denotes the radius of the circle and c is the angle subtended at the center. Statements: Equal chords subtends equal angles at the centre of the circle, i.
