If a straight line intersects two or more parallel lines, then it is called a transversal line. When the coplanar lines are cut by a transversal, some angles are formed. Those angles are known as interior or exterior angles. Alternate angles are shaped by the two parallel lines crossed by a transversal.
Consider the given figure,
EF and GH are the two parallel lines.
RS is the transversal line that cuts EF at L and GH at M
If two parallel lines are cut by a transversal, then the alternate angles are equal.

Therefore, ∠3 = ∠ 5 and ∠4 = ∠6
∠2 = ∠8 and ∠1 = ∠7.
