## Is secant and chord of a circle the same thing?

A circle is a closed loop. In a circle, every point on the circle is at an equal distance from the centre O. In a secant, the line intersects the circle at two points….Difference between a secant and a chord.

Secant Chord
It is drawn from outside the circle It lies within the circle

## What are the similarities and differences of a chord a secant and a tangent of a circle?

A chord is a line segment and both secant and tangents are straight lines. Chord is a line segment with the end points lying on a curve while a secant is a line passing through exact two points on a curve. A tangent is a line that just touches and passes through a point on a curve.

## How are the tangent secant and chord of a circle related?

A line will meet a circle at no more than two points. We call a line a secant if it intersects twice, and a tangent if it intersects once (just touching at a single point). Chords are segments connecting two points on a circle, so chords become secants when extended.

## How are chords and Secants of circles alike How are they different?

A chord is a segment whose endpoints are on a circle. A diameter is a chord that contains the center of the circle. A secant is a line that intersects a circle in two points.

## How do you calculate chords?

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)

210 chords

## How many radius can a circle have?

The distance between the center of the circle and its circumference is referred to as its radius. We can draw as many radii to a point on the circle by joining the center. Thus every circle has an infinite number of radii.

## How many diameters are in a circle?

A radius of a circle is a segment with one endpoint on the circle and the other endpoint at the center of the circle. There is only one diameter drawn on circle C. However, every circle has an infinite number of possible diameters.
