  1. Geometry Unit II 3.3 Part 2 Partial Proofs Involving Parallel Lines

  2. given postulate Theorem definition Linear pairs A ray that divides an angle into two adjacent angles that Are congruent. Two angles whose measures add up to 180 degrees

  3. Two parallel lines The pairs of corresponding angles are congruent Their sum = 180 degrees Replacing one quantity with an equivalent one. They are congruent The pairs Of AIA are congruent The pairs Of AEA are congruent The pairs Of SSIA are supplementary.
