Question

1. (13) is the following sentence true? according to betweenness of points, if points a, b, and c are collinear and ab + bc = ac, then c is between a and b. a. yes b. no c. maybe d. sometimes e. not applicable 2. (19) two rays joined together so that they have the same endpoint make a(n) __. a. angle b. square c. circle d. triangle e. none of the above 3. (112) the midpoint of a line segment is the point that divides the line segment into __ congruent line segments. a. five

Explanation:

Step1: Recall between - ness property

If points A, B, and C are collinear and C is between A and B, by the segment - addition postulate, AB + BC=AC. So the answer to question 1 is Yes (A).

Step2: Analyze ray - combination

When two rays are joined together so that they have the same endpoint, they form an angle. So the answer to question 2 is angle (A).

Step3: Recall mid - point definition

The mid - point of a line segment divides the line segment into two congruent line segments. So the answer to question 3 is congruent line segments (A).

Answer:

1. A. Yes
2. A. angle
3. A. congruent line segments
