Statements Reasons1. Line l parallel to Line m    Line t is a transversal    Angles a, b, c, d as drawn.

2.  Angle a is congruent to angle b.

3. Angle b is congruent to angle c.

4. Angle a is congruent to angle c.

1.  Given

2.  Vertical angles are congruent.

3.  If parallel lines are cut by a transversal,     then alternate interior angles are congruent.

4.  Transitive Property of Congruence
