Statement Reason
PLAN: alternate interior angles
1. AB ll DE & BC ll EF 1. Given
2. <z = <e 2. If parallel lines are cut by a transversal then alternate interior angles are equal in measure
3. <z = <b 3. If parallel lines are cut by a transversal then alternate interior angles are equal in measure
4. <e = <b 4. Substitution property of equality

PLAN: corresponding angles
1. AB ll DE 1. Given
2. Auxiliary lines m, m ll AB ll DE
2. Drawn
3. <v + <w = <z 3. Angle Addition postulate
4. <v = <x <w = <y
4. If parallel lines are cut by a transversal then corresponding angles are equal in measure
5. <z = <x + <y 5. Substitution Property of Equality

PLAN:Statement Reason
1. AB ll CD & BC ll DE 1. Given
2. <1 = <3 2. If parallel lines are cut by a transversal then alternate interior angles are equal in measure
3. <2 = <3 3. If parallel lines are cut by a transversal then alternate interior angles are equal in measure
4. <1 = <2 4. Substitution property of equality
alternate interior angles

Statement Reason
PLAN:
1. AB ll CD & BC ll DE 1. Given
2. If parallel lines are cut by a transversal then same side interior angles are supplementary
2. <1 + <d = 180
3. <1 = <b 3. If parallel lines are cut by a transversal then same alternate interior angles equal
4. <1 + <d = 180 4. Substitution Property of Equality
alternate interior angles same side supplementary
