Problem
(2) In the figure below, \( A, B, C \), and \( D \) each represent the angle measure of their respective angle positions. Which statement is NOT true about the angle measures? \( A+B=D \) (2) \( C+D=A \) \( A+B=180^{\circ} \) (D) \( B+C+D=180^{\circ} \)
Solution
Step 1 ：(1) \( A+B=D \)
Step 2 ：(2) \( C+D=A \)
Step 3 ：(3) \( A+B=180^{\circ} \)
