You can put this solution on YOUR website!
1. Reason: Given
2. Reason: Since line m and line n are parallel, corresponding angles are congruent
3. Reason: Congruent angles have equal measure
4. Reason: A linear pair is formed when two straight lines intersect.
5. Reason: Linear pairs of angles are supplementary.
6. Reason: Supplementary angles add to 180 degrees.
7. Statement: m_angle3 + m_angle1 = 180 degrees Reason: Substitution (statement #6 and statement #3)
8. Statement: angle3 is supplementary to angle1 Reason: angles that add to 180 degrees are supplementary
