Answer:
Step-by-step explanation:
Although the reasons are not given in this question, find the possible statements and reasons for this question.
Statements Reason
1). y ║ z 1). Given
2). ∠1 ≅ ∠5 2). Alternate interior angles theorem
3). ∠3 ≅ ∠6 3). Alternate interior angles theorem
4). ∠1 + ∠2 + ∠3 = 180° 4). Linear angles
5). ∠5 + ∠2 + ∠6 = 180° 5). Substitution property
Therefore, sum of the interior angles of a triangle is 180°.
