1-2 Measuring Segments

Question 1

distance

Answer 1

the straight measurable length from one point to another

Question 2

coordinate

Answer 2

a real number line that matches or corresponds to that point

Question 3

between

Answer 3

if three collinear points exist then the point somewhere in the middle is said to be between the other two points

Question 4

congruent segments

Answer 4

if the length of two line segments are equal then the two line segments themselves are congruent

Question 5

midpoint

Answer 5

the midpoint of a segment is the point that divides the segment into two smaller segments

Question 6

segment bisector

Answer 6

a point line ray segment or plane that intersects a line segments midpoint

Question 7

ruler postulate

Answer 7

if two points that have coordinates on a number line are corresponding to each of two values for those coordinates then the distance between those two points is the absolute value of the difference of the values

Question 8

segment addition postulate

Answer 8

if there are three collinear points on a line then the length of the segment between the first last points is equal to the sum of the lengths of the other smaller 2 segments
