## Is a circle a line?

A circle is a type of line. Imagine a straight line segment that is bent around until its ends join. Then arrange that loop until it is exactly circular – that is, all points along that line are the same distance from a center point.

## Is a ring a shape?

## Is it herniated disc or disk?

A herniated disc (also called bulged, slipped or ruptured) is a fragment of the disc nucleus that is pushed out of the annulus, into the spinal canal through a tear or rupture in the annulus. Discs that become herniated usually are in an early stage of degeneration.

## Is Circle 2d or 3d?

The circle is a two-dimensional (2D) shape. It only has two measurements, such as length and height, and is usually called a ‘flat’ shape. The ball, however, is a three-dimensional (3D) shape because it has three measurements (length, height, and width) and is sometimes called a ‘solid’ shape.

## Which diamond shape is best?
