Linear Measure

2. Line segment – part of a line with two endpoints and all points between them__
The measure of AB is always written as AB.

3. Betweenness of points – for any 2 points there is another point between them
Point M is between points P and Q if and only if P, Q, and M are collinear and PM + MQ = PQ

4. Congruent segments – have the same measure

5. Constructions
Constructions are drawings of geometric figures made without measuring tools.
Usually made by only using a straight edge, compass, and pencil.
Sketches are made with no tools.

7. Section 1.3
Distance and Midpoint

8. Distance
On the number line, distance between two points is the absolute value of the difference between their coordinates.
d =

9. In the coordinate plane, distance is found by using:
_______________
d= √ (x2-x1)2 + (y2-y1)2

10. Midpoints
This is basically the average between two points.
M =

11. Segment bisector – any segment, line, or plane that intersects a segment at its midpoint
