    Study Notes

    Parallel Line Proofs

    • Parallel line proofs involve showing that two lines are parallel by using the properties of angles formed by transversals.
    • The first step in writing a parallel line proof is to identify the given information and the conclusion to be proved.

    Arcs in Diagrams

    • The purpose of using arcs in the diagram is to denote corresponding angles, alternate interior angles, or same-side interior angles.

    Angles in Proofs

    • The converse of alternate interior angles is that if two lines are parallel, then alternate interior angles are congruent.
    • One way to prove lines are parallel in a parallel line proof is to show that corresponding angles are congruent.
    • The angles that are given as supplementary in the proof are same-side interior angles.
    • The angles mentioned in the given statement are alternate interior angles.

    Continuing the Proof

    • To continue the proof, we need to find a pair of congruent angles to use as a transitive property to prove that the lines are parallel.
