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.
