Question

In the figure, 

x∥y
 and a is a transversal that crosses the parallel lines.
Which angle pair forms alternate interior angles?


∠3
and
∠7

∠1
and
∠8

∠4
and
∠6

∠2
and
∠6

Answer 1

<4 and <6 is the answer I am very good at this type of math

Answer 2

∠4 and ∠6

Explanation:

we know that

Alternate interior angles are two interior angles which lie on different parallel lines and on opposite sides of a transversal

In this problem

m∠3=m∠5 --------> by alternate interior angles

m∠4=m∠6 --------> by alternate interior angles

therefore

the answer is

∠4

and

∠6
