Tip #1

As long as two or more angles are equal (i.e. the same), these angles are congruent. This is true regardless of the arms length, position or the orientation of the angles. For example, the angles below are congruent:

Math Video Transcript

In this lesson, we will learn about angles that are congruent.

Let's take a look at these two angles.

Notice that, these two angles are equal.

Hence, these angles are called, congruent.

Now, if the arms' length are not the same, but the angles remain equal, these angles are still congruent.

Similarly, if the orientation is not the same, but the angles are equal, the angles are still congruent.

Now, let's see some examples.

Are these angles congruent? Yes, they are.

Next, how about these angles? Yes again.

Last example, are these congr. angles?

Since these angles are not equal, they are not congruent.

That is all for this lesson.
