Question 10

Segment

Answer 10

A part of a line. It contains two and points and connect them

Question 11

Ruler Postulate

Answer 11

Subtract the end point values and take the absolute value of the difference

Question 12

Point Between

Answer 12

A point is between two other points only if all three points are collinear (The point does not have to be the midpoint)
