Is it correct to say circumference?

We are here to explain to you what an arc in a circle is in the easiest and most logical way.

First, let's remember what the shape of an arc is...

When you look up at the sky and see a rainbow, it looks like this, right?

**How about a hair tie? It looks quite similar as well:**

Now that we remember the shape of the arc, it will be easier for us to remember what an arc in a circle is.

An arc in a circle is the part between $2$ points on the circle.

Pay attention: the arc is on the circle and not inside it. It is part of the circumference of the circle and closely resembles the rainbows we see in everyday life.

**Let's show it in the figure:**

In front of us is a circle.

If we take $2$ points on top of the circle, for example, $A$ and $B$,

the part of the circle between these two points will be an arc.

Pay attention that we do not draw a line between the points inside the circle (a chord)

but rather we paint the top part of the circle as part of its circumference.

**Note:**

The arc can be of any length and even if it does not remind us of the arc we see in everyday life, it will still be an arc in a circle.

While it is on the circle between $2$ points as part of the circumference, the circle is called an arc.

**We will see examples where the arc in the circle does not look like an arc shape:**
