What is a coordinate?
The absolute value of the difference of 2 coordinates
What is the distance?
-2, 4
What is 6?
If Y is between X and Z, and XZ = 23 and YZ = 7, XY is this
What is 16?
These 3 letters remind you of Step 3 in solving segment addition problems
What are CLT?
The distance between 2 points
What is the length?
This point divides the segment into 2 congruent segments
What is the midpoint?
0, 7
What is 7?
If R is between Q and S, and QR = 4 and RS = 5, QS is this
What is 9?
This suggestion was Mr. Mac's first when it comes to solving segment addition problems
What is write out the segments according to the Segment Addition postulate?
For a point to be in this position with 2 other points, ALL three points MUST lie on the same line
What is between?
Any ray, segment, or line that intersects a segment at its midpoint
What is a segment bisector?
-13, -2
What is 11?
If U is between T and V, and TV = 11 and TU = 7, UV is this
What is 4?
Another important step is to do this with variables and numbers
What is separate the variables from the numbers?
This word means divide
What is bisect?
Points on a line can be matched to corresponding real numbers on a ruler or number line
What is the Ruler Postulate?
-23, -6
What is 17?
If B is between A and C, and BC = 10 and AC = 13, AB is this
What is 3?
After diagramming your segments, the next step is this
What is plug in the numbers and variables into the equation?
Segments that have the same length
What are congruent segments?
The postulate that states if Point B is between Points A and C on a line segment, then the sum of the lengths of segment AB and segment BC equals the length of AC
What is the Segment Addition Postulate?
6, 22
What is 16?
If E is between D and F, and DE = 7 and EF = 8, DF is this
What is 15?
To separate a variable and a number, like 3x or 4 + x/2, you may have to do these 2 concepts
What are divide and multiply?
