Answer:
Two pairs of alternate interior angles are→1) ∠3 , ∠5 and ∠4 , ∠6
and 2) ∠7 , ∠9 and ∠8 , ∠10
Four pairs of corresponding angles are → 1) ∠1 , ∠5 and ∠2 , ∠6
2) ∠4 , ∠8 and ∠3 , ∠7
3) ∠5 , ∠9 and ∠6 , ∠10
and 4) ∠8 , ∠12 and ∠7 , ∠11
Step-by-step explanation:
When two parallel line cuts by a another line (transversal).Then,
Alternate interior angles → it is the pair of a angles on the inner side of each of those two lines but on opposite sides of the transversal.
hence in the given figure
1)∠3 , ∠5 and ∠4, ∠6 and 2)∠7 , ∠9 and ∠8 , ∠10 are two pairs of alternate interior angles.
Now,
Corresponding angles → the angles are the ones at the same location at each intersection.
Hence in the given figure
1) ∠1 , ∠5 and ∠2 , ∠6 2) ∠4 , ∠8 and ∠3 , ∠7 3) ∠5 , ∠9 and ∠6 , ∠10 and 4) ∠8 , ∠12 and ∠7 , ∠11 are four pairs of corresponding angles.
