No; actually, the diameter is a chord that goes through the center of a circle.

Q: Is a chord always equal to the length of the diameter?

The length of the diameter is always twice the length of the radius.

NoneAdditional Information:-Unless it is the diameter of the circle which is its the largest chord then it will have a length equal to two radii (but the chord itself has no radii).

Because in effect an isosceles triangle has been constructed and the base angles are always equal.

It's a chord, unless the 2 parts are equal, when it becomes a diameter.

Not always.

No but the diameter is the largest chord in a circle.

The length of the diameter is always twice the length of the radius.

It is equal to a diameter of 10.5 units of length.

Yes, any diameter which is perpendicular to a chord bisects said chord. This can be proved most easily with a picture, but is proved using a congruent triangle proof. Both triangles include the points at the center of the circle and the intersection of the diameter and chord. The other points should be the endpoints of the chord. They are congruent by hypotenuse leg; it was given that they are right triangle by the "perpendicular", the "leg" is the segment between the center of the circle and the intersection, and it is equal in both triangles because it is the same segment in both triangles. The hypotenuses are equal because both are radii of the circle. Because the triangles are congruent, their sides must be so the two halves of the chord are congruent, and therefore the chord is bisected by the diameter.

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.

That's right. In a circle, the length of a diameter will be the same as twice the length of a radius.

No, the radius of a circle is always 1/2 of the diameter.

Yes, because the side a and side c are always equal in length and side b and side d are always equal in length.
