Next \( \Theta \quad \) Pretest: Linear Relationships in Geometry I1 The coordinates of the endpoints of \( \overline{A B} \) and \( \overline{C D} \) are \( A(3,6), B(8,7), C(3,3) \), and \( D(8,4) \). Which statement describes how \( \overline{A B} \) and \( \overline{C D} \) are related? A. \( \overline{A B} \| \overline{C D} \) O B. \( \overline{A B} \perp \overline{C D} \), and \( \overline{A B} \) bisects \( \overline{C D} \) O C. \( \overline{A B} \perp \overline{C D} \), but \( \overline{A B} \) does not bisect \( \overline{C D} \). O D. \( \overline{A B} \) is neither paralel nor perpendicular to \( \overline{C D} \).
