What is angle 5 compared to angle 8 Alternate interior anges Alternate exterior angles Corresponding angles Vertical angles Supplementary angles?

Answer: supplementary angles

Assuming that the two lines are parallel:
Alternate interior angles
<5 and <7
<6 and <8

Alternate exterior angles
<3 and <9
<4 and <10

Corresponding angles
<4 and <8
<5 and <9
<3 and <7 
<6 and <10

Vertical angles
<3 and <5
<6 and <4
<7 and <9
<8 and <10

Supplementary angles
<3 and <4
<4 and <5
<3 and <6
<6 and <5
<7 and <8
<8 and <9
<9 and <10
<7 and <10
<6 and <7
<5 and <8
