Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(1,3), H (2,1), J(-1,-5), and K (-2,-3) what are the coordinates

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
