p56
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

Statement Reason
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
