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
