Answer:

∠2   =  ∠3 is a pair of  Vertical Angles.

Step-by-step explanation:

Whenever two lines intersect with each other, the angle formed between them is called Vertically Opposite Angle.

Here, line l intersects the traversal so,

the angle formed between them  ∠1 and ∠4 are vertically opposite.

So, ∠1 =  ∠4

Also, as ∠1 +  ∠3 =  ∠2  + ∠4 = 180°  (LINEAR PAIRS)

So,  ∠3   =  ∠2 are also vertical angles.
