Then angles 5 and 7 , first
They are alternate, 5 is exterior and 7 interior. They are called CORRESPONDING angles
Second angles 2 and 7
they are angles ALTERNATES INTERIOR ( A.I)
Now angles 1 and 3
they are CORRESPONDING angles, because they are on the same line ubication
Finally angles 5 and 8
they are exterior both, consecutive and at the same-side
So they are (C.E ) and S.S.E
