6. What are the extremes of the following proportion?
3/45 = 1260
O A. 15 and 12
O B. 3 and 15
O C. 12 and 60
O D. 3 and 60

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
