Using the figure below, tell if the triangles are congruent, and if so by what theorem? a. Yes, they are congruent by SSS theorem.
b. Not enough information to answer the question.
c. Yes, they are congruent but there is not a reason why..
d. No, they are not congruent.

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
