True or false: Vertical angles are the top and bottom angles of the four angles formed by two intersecting lines.

True

Step-by-step explanation:

When two lines intersect each other at the vertex (known as point of intersection), four angles are formed . The angles that are opposite from each other are known as a pair of vertical angles and they are always equal.So, left and right angles must be equal (i.e. ∠3=∠4) and top and bottom angles are equal (i.e. ∠1=∠2) .

Hence, the given statement is correct .

so, the answer is "True".
