Can a chord of a circle also be the diameter of the circle?
Sure. Any chord that passes through the center of the circle is also a diameter. Chords can have many different lengths, but a diameter is the longest chord.
Why is the diameter the longest chord?
A chord is a straight line from one point on a circle's circumference to another. Because the largest straight line distance in a circle is the diameter and the diameter is also a chord, the diameter is the longest chord. Join the endpoints of a given chord to the center of the circle to form an isosceles triangle. The triangle inequality then tells that the length of the chord is less than two radii of the circle, i.e., less than the diameter. See related links.
What does diamater mean?
The diameter is the chord (line that goes from the circle to the circle) that goes through the center of the circle. It is the largest chord. It is also equal to twice the radius.
What is the chord that passes through the centre of a circle?
The chord that passes through the center of a circle is called the diameter. The measure of this chord is also called the diameter, and is used in calculations such as finding the circumference of a circle (Circumference equals pi times the diameter).^^wrong...it is eitherSecant or tangent im pretty sure its SECANT though...
Is the radius of a circle a chord also?
No. A chord is a straight line joining two points on the circumference of a circle whereas a radius joins only one point on the circumference to the circle centre. A diameter is a straight line joining two points on the circumference (via the circle's centre) and so is also a chord. (Yes, but the question is about a radius, not a diameter!)
