Is chord a diameter?

A chord that passes through a circle’s center point is the circle’s diameter. The word chord is from the Latin chorda meaning bowstring.

Is chord a diameter yes or no?

(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.

Why is a chord not a diameter?

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center.

What is the difference between diameter and chord of a circle?

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.

Where is the chord in a 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.

How do you find the diameter of a chord?

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. We will use Pythagoras theorem to find the radius of a circle with a chord.

What does a chord of a circle look like?

Video quote: We call the diameter right dimer now the look this is a special type of what we call a cord and the basic definition of a cord is just going to be any line. That's two endpoints. And on the circle.

What is a chord line in a circle?

In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle. The term is also used in graph theory, where a cycle chord of a graph cycle is an edge not in whose endpoints lie in .

What happens to the chord when a diameter is drawn in a circle?

Theorems about chords and diameters in a circle and their converses: If a diameter of a circle bisects a chord, then it must be perpendicular to the chord. If a diameter of a circle is perpendicular to a chord, then it bisects the chord. If two chords are congruent, then the center is equidistant from the two chords.

What is the example of chord?

A line segment connecting two points on a curve. Example: the line segment connecting two points on a circle’s circumference is a chord. When the chord passes through the center of a circle it is called the diameter.

How many chords are in a circle?

R D Sharma – Mathematics 9



2 chords divide a circle into 4 regions.

How many diameters are in a circle?

It is half the length of the diameter of a circle, i.e., Radius = Diameter/2. The diameter of a circle is a line segment that passes through the center of a circle and has two endpoints at the circumference. It is twice the length of the radius of a circle, i.e., Diameter = 2 × Radius.

Can a chord be contained in a secant?

A chord is the line segment that joins two distinct points of a circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.

What is chords in circuit?

When, a graph is formed from an electric network, some selective branches are taken. The branches of the network which are not in tree formation are referred as links or chords. The graph formed by these links or chords is called cotree. Cotree can be closed or opened depending upon the links.

What is a chord in graph theory?

In the mathematical area of graph theory, a chordal graph is one in which all cycles of four or more vertices have a chord, which is an edge that is not part of the cycle but connects two vertices of the cycle.

What is tree and Cotree?

A tree is a connected sub graph of a network which consists of all the nodes of the original graph but no closed paths. The number of nodes in the graphs is equal to the number of nodes in the tree. Co-tree: It is a sub graph which is formed after disconnecting a tree from the given graph.

What is node and branch?

Branch represents a single circuit element like resistor, voltage source etc. Node is a point in a network where two or more circuit elements are connected.

How do you identify a node?

A node is usually indicated by a dot in a circuit. If a short circuit (a connecting wire) connects two nodes, the two nodes constitute a single node.

What is a loop and node?

What is the node branch and loop in a circuit? A node is the point of connection between two or more branches. A branch represents a single element such as a voltage source or a resistor. A loop is any closed path in a circuit.

Are loops branches?

Loops in Electric Circuit



If one starts from one node and after going through a set of nodes returns to same starting node without crossing any of the intermediate node twice, he has travels through one loop of the circuit. Loop is any closed path in the circuit formed by branches.

What is the difference between a mesh and a loop?

A loop is any closed path through a circuit where no node more than once is encountered. A mesh is a closed path in a circuit with no other paths inside it.

What is difference between loop and branch?

A branch is any element connected between two nodes. R4 and R3 are examples of a branch. A loop is any sequence of elements connected between nodes that starts and ends at the same node. You only include a node once in a loop.
