GEOMETRY 12.12.11 NAME Theorem 3.7.1 If corresponding angels are equal, then the lines are parallel. To prove: l ∥ m. Given: ∠a = ∠b. T is a transversal. See diagram on p. 90. Statement Reason 1. ∠a = ∠b. 2. T is a transversal. 3. ∠a = ∠c. 4. ∠b = ∠c. 5. ∴ l ∥ m. AXIOM AND THEOREM BANK Quantities which are equal to the same quantity are equal to each other. If a transversal intersects two lines so that the alternate interior angles are equal, then the lines are parallel. Vertical angles theorem. Given.
