Which statement is true of ∠1 only if AA' is perpendicular to BB′?

• 
  It is equal in measure to ∠4.

Look at the number line. Two points A and B have weights w_A and w_B respectively. Their weighted average is w. If, the weight of A is changed to 2w_A, while that of B remains the same, which statement is true about the new weighted average w′ of A and B?

• w' lies after B

• w" lies before A

• w' lies between A and w

• w' lies between w and B
