Answer

Yes, segments ( \(AB\) ) and ( \(CD\) ) are congruent. Explanation 1. Identify Congruent Segments Check if segments ( ( \(AB\) ) ) and ( ( \(CD\) ) ) are congruent by calculating their lengths using the distance formula. 2. Calculate Length of Segment AB Use **distance formula**: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}. For ( ( \(AB\) ) ), d_{AB} = \sqrt{(6 - 6)^2 + (1 + 8)^2} = \sqrt{81} = 9. 3. Calculate Length of Segment CD For ( ( \(CD\) ) ), d_{CD} = \sqrt{(7 + 2)^2 + (-2 + 2)^2} = \sqrt{81} = 9. 4. Compare Lengths Since \(d_{AB} = d_{CD}\), segments ( ( \(AB\) ) ) and ( ( \(CD\) ) ) are congruent.

1. Identify Congruent Segments<br /> Check if segments ( \(AB\) ) and ( \(CD\) ) are congruent by calculating their lengths using the distance formula.<br /><br />2. Calculate Length of Segment AB<br /> Use **distance formula**: $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$. For ( \(AB\) ), $d_{AB} = \sqrt{(6 - 6)^2 + (1 + 8)^2} = \sqrt{81} = 9$.<br /><br />3. Calculate Length of Segment CD<br /> For ( \(CD\) ), $d_{CD} = \sqrt{(7 + 2)^2 + (-2 + 2)^2} = \sqrt{81} = 9$.<br /><br />4. Compare Lengths<br /> Since \(d_{AB} = d_{CD}\), segments ( \(AB\) ) and ( \(CD\) ) are congruent.
