Consider the two statements:

Statement 1: The points A, B, and C will lie on a straight line if $∠ A B D$ + $∠ C B D$ = $180^{\circ}$ .

Statement 2: The angle on a straight line is $180^{\circ}$ .

With reference to the figure below, consider the two statements:

Statement I: The points A, B, and C will lie on a straight line if x + y = $180^{\circ}$ .

Statement II: If the angle between two lines is $180^{\circ}$ , then all the points on both the lines lie on a straight line.
