Answer:
<u> Consecutive Interior Angles </u>
Consecutive interior angles equal 180 degrees and they are the ones in between(inside) the parallel lines, so that means that these angles..
∠2+∠9= 180
∠4+∠11= 180
∠6+∠13= 180
∠8+∠15= 180
<u> Consecutive Exterior Angles </u>
Consecutive exterior angles also equal 180 degrees, but they are on the outside of the parallel lines. They are...
∠1+∠10= 180
∠3+∠12= 180
∠5+∠14= 180
∠7+∠16= 180
