Is it a curve?

Open in App
Solution

Closed curves are the shapes that are closed by line-segments or by a curved line.

e.g. A circle is an example of such a closed curve.

The shape which is not closed by line-segments or a curve is called an open curve, e.g. figure 1.

Figure 2 doesn't have endpoints and it completely encloses an area.

Hence, it is a curve.
