we have that
alternate exterior angles
< 1 and <5
<2 and <6
alternate interior angles
<3 and <7
<4 and <8
same side interior angles
<3 and <4
<7 and <8
corresponding angles
<1 and <7
<8 and <6
<2 and <4
<3 and <5
Pairs that are congruent------> all pairs are congruent except same side interior angles)
< 1 and <5
<2 and <6
<3 and <7
<4 and <8
<1 and <7
<8 and <6
<2 and <4
<3 and <5
pairs that are supplementary (same side interior angles)
<3 and <4
<7 and <8
