Determine if lines that pass through the given points are parallel, perpendicular or neither. line a: (5, 4) and (7, 5) line b: (4, -5) and (8, -3) a) parallel b) perpendicular c) neither d) cannot be determined

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
