Suppose a hexagon with the vertices ( − 2 , 1 ) , ( − 1 , − 1 ) , ( − 1 , 3 ) , ( 1 , − 1 ) , ( 1 , 3 ) , and ( 2 , 1 ) were rotated 180 ° about the origin. Which of these would be a vertex of the rotated figure? Select all that apply. A. ( − 3 , 1 )
B.(2,-1)
C.(-1,-1)
D.( − 1 , 1 )
E. ( 1 , − 3 )
F. ( 1 , 2 )

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
