1.1.2 Measuring and Constructing Segments

Question 1

coordinate

Answer 1

a number used to identify the location of a point. On a number line, a point corresponds to one number
and this number is called a coordinate

Question 2

distance

Answer 2

between any two points is the absolute value of the difference of the coordinates

Question 3

length

Answer 3

The distance between two points A and B is also called the length of AB.

Question 4

congruent segments

Answer 4

segments that have the same length

Question 5

construction

Answer 5

a way of creating a figure that is more precise than a sketch. In order for you to say that a point B is between two points A and C, all three of the points must lie on the same line, and AB + BC = AC

Question 6

midpoint (M)

Answer 6

of a segment AB is the point that bisects, or divides, the segment into two congruent segments. If M is
the midpoint of segment AB, then AM = MB

Question 7

bisect

Answer 7

to divide into two congruent parts

Question 8

segment bisector

Answer 8

any ray, segment, or line that intersects a segment at its midpoint

Question 9

Ruler Postulate

Answer 9

The points on a line can be put into a one-to-one correspondence with the real numbers

Question 10

Segment Addition Postulate

Answer 10

If B is between A and C, then AB + BC = AC
