To do this, she sketched out a pair of parallel line segments and formed a triangle in between those lines. She then wrote the first few statements to try to prove this.

Statement Number Statement
1 ∠1+∠2+∠3=180°
2 ∠2≅∠4
3 ∠3≅∠6
4 ∠4+∠5=180°
5 ∠4+∠6=180°

A Statement 1

B Statement 2

C Statement 3

D Statement 4

E Statement 5
