In this lesson, we will learn about this type of angle

Let's take a look at this angle.

Now, when this angle is somewhere between 180 degrees and 360 degrees, it is called a rfx angle.

In other words, a rfx angle is always more than 180 degrees and less than 360 degrees.

Let's see some examples on this.

This is a 230 degrees angle. Is this a rfx angle?

Yes! It is.

Next example, take a close look at this angle. Is this a rfx angle?

We know that a rfx angle is more than 180 degrees.

Since this angle is not more than 180 degrees, it is not a rfx angle.

Next, how about this angle?

Clearly, it is a rfx angle.

That is all for this lesson.
