**What can you say about the measures of two vertical angles?**

The measures of two vertical **angles are equal.**

Two vertical angles.

**Vertical angles are angles that are formed opposite to each other when two lines intersect at a point. **

In the above figure, the two lines intersect at a point to form four angles $\angle 1,\text{}\angle 2,\text{}\angle 3,$ and $\angle 4$. Among the four angles, $\angle 1$ and $\angle 3$ are vertical angles and their measures are equal. Similarly, $\angle 2$ and $\angle 4$ are vertical angles and their measures are equal too.

Therefore, it can be said that the measures of two vertical angles are equal.
