Which lines can you conclude are parallel given that m∠7 + m∠11 = 180? Justify your conclusion with a theorem. Line a is parallel to line b by the Converse of the Alternate Interior Angles Theorem.Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.Line c is parallel to line d by the Converse of the Alternate Interior Angles Theorem.Line c is parallel to line d by the Converse of the Same-Side Interior Angles Theorem.7 + m∠

Answer:Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.Step-by-step explanation:find out the statement that conclude are parallel given that m∠7 + m∠11 = 180angle 7 and 11 are the consecutive interior angles . that is same side interior angles.angle 7 and 11 are the consecutive interior angles and they are supplementary when the lines are parallel.Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.
