Answer
a) True
b) False
Work Step by Step
a) In the given diagram below, we see that point B is in the middle of points A and D. Since the three points are collinear, we know that B will be in the middle when the line is drawn through all three points.
b) Since A, B, and C are not collinear, we cannot say that B is between points A and C. Thus, the given statement is false.
