1. Day 3 Measuring Segments and Angles

2. Measuring Segments and Angles
Find KN EX: 7 13 KN = distance between K and N or the length of KN = the name of the segment between K and N Find a length or distance on a number line =

3. Congruent Segments: segments that are the same length.

4. Segment Addition Postulate: If A, B, and C are collinear and B is between A and C Then AB + BC = AC

5. Midpoint of a segment
On a # line: The midpoint splits the segment in exactly half!

6. Segment Bisector: A figure that passes through the midpoint of a segment.

7. Examples:
W is between V and X, VW = 3x+5, WX=2x+10 and VX = 50. Find VW.

8. 2. K is the midpoint of . JK = 2x+1 and KL=3x-4. Find JL.

9. 1-4 Measuring Angles
Angle: is formed by two rays with the same endpoint. The rays are the SIDES of the angle. The endpoint is the VERTEX of the angle. EX NAMES: <ABC <CBA <1

10. Angle Addition Postulate

11. Angle Bisector
Is a ray that divides an angle into two angles. ____ bisects _______, therefore_____________
