Which related equation can be used to solve the equation? column a column b 1. –8.7 = k + 6 2. –6 = k + 8.7 3. 8.7 = k + (–6) 4. 6 = k + 8.7 a. k = –8.7 – 6 b. k = 6 – 8.7 c. k = 8.7 – (–6)

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
