StatementReason
1Construct DE↔\overleftrightarrow{DE}DE
D, E, with, \overleftrightarrow, on top through parallel to AC↔\overleftrightarrow{AC}AC
A, C, with, \overleftrightarrow, on top. Given a line, we can construct a parallel line through a point not on the given line.
2m∠A=m \angle A=m∠A=m, angle, A, equals
Alternate interior angles formed by parallel lines have equal measures.
3m∠B=65°m \angle B=65 \degreem∠B=65°m, angle, B, equals, 65, degreeGiven
4m∠C=m \angle C=m∠C=m, angle, C, equals
Alternate interior angles formed by parallel lines have equal measures.
5m∠A+m∠B+m∠C=180°m \angle A + m \angle B + m \angle C = 180 \degreem∠A+m∠B+m∠C=180°m, angle, A, plus, m, angle, B, plus, m, angle, C, equals, 180, degreeSubstitution and addition (2, 3, 4).
Did we prove the conclusion true for every triangle or only for this specific triangle?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
