Sorry, I can't explain it well but I hope that with the use of the figure that I attached, it'll help. 

On the figure, the corresponding angles are the ff.:
∡1 & ∡3
∡2 & ∡4
∡5 & ∡7
∡6 & ∡8

The other angle is outside the parallel lines while the other one is inside the parallel lines and both are on the same sides. Also, corresponding angles are congruent. 

I hope it help. ☺

1,3, 6 and 8 have the same obtuse angle while 2, 4, 5 and 7 have the same acute angel.

alternate interior angles are 6&3 , 7&2

consecutive interior angles 2&3, 6&7

alternate exterior angles 4&5, 1&8

Hi, which are the corresponding angles in your answers?  Please clarify :-) Thanks.  By the way, is that image yours or from previous answer (JoecelE's)?
