In this lesson, we will learn about vert. angles.

00:00:10.210

When these two lines intersect, we will get a pair of non-adjacent angles.

00:00:17.210

Now, if we observe carefully, we can see that these two angles are congruent angles.

00:00:24.120

This means that, these two angles are the same.

00:00:29.050

Therefore, this angle will be 50 degrees.

00:00:34.120

Now, there is another pair of vert. angles.

00:00:39.130

Since this angle is 130 degrees, this angle must also be, 130 degrees.

00:00:47.120

Alright, when we rotate this line, take note of the vert. angles.

00:00:58.200

Let's look at some examples.

00:01:02.020

Are these vert. angles?

00:01:05.160

Yes! It is. Next example, this angle is 150 degrees. Find x.

00:01:18.200

Now, we know that these angles are vert. angles.

00:01:23.100

Hence, these two angles must be congruent.

00:01:27.130

Therefore, x must be equals to, 150 degrees.

00:01:33.160

That is all for this lesson.
