What is the following difference?
2ab(V192ab?)-s(/81a*b*
-3ab[3ab?
16ab? (1/3a) - 45a_b? (2/3)
-7a6f3ad?
Bab V3ab? ) - 15ab? (1/320)

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
