About This Lesson
In this lesson, we will:
- What are vertical angles.
- See some examples on identifying them.
The study tips below will give you a short summary on this.
The math video below will explain in depth about this. Furthermore, it will show some examples so that you can understand this lesson better.
There are several properties that we must identify to see whether two angles are vertical angles. These conditions are shown in the picture below:

In this lesson, we will learn about vert. angles.
When these two lines intersect, we will get a pair of non-adjacent angles.
Now, if we observe carefully, we can see that these two angles are congruent angles.
This means that, these two angles are the same.
Therefore, this angle will be 50 degrees.
Now, there is another pair of vert. angles.
Since this angle is 130 degrees, this angle must also be, 130 degrees.
Alright, when we rotate this line, take note of the vert. angles.
Let's look at some examples.
Are these vert. angles?
Yes! It is. Next example, this angle is 150 degrees. Find x.
Now, we know that these angles are vert. angles.
Hence, these two angles must be congruent.
Therefore, x must be equals to, 150 degrees.
That is all for this lesson.
