Match the algebraic addition of each pair of complex numbers to its sum represented graphically. (-3 +51) + (2 +31) (3 +51) + (2-31) (-3+51) + (-2 - 31) (3-51) + (2 + 31)

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
