1. DAY3: 1-3 Measuring Segments

2. distance or DISTANCE IS ALWAYS POSITIVE and

3. Segments of the same length midpoint segment bisector tic marks

5. between AB + BC=AC Part + = WHOLE APE AP + PE =AE

6. Part + = WHOLE APE AP + PE =AE 3x x+5 AE=25 x= AP= PE= (3x) + (x+5) =25 4x+5 =25 x=5 5 15 25 AP=3(5)PE=(5)+5

7. Part = 8x+11=12x – 1 12 = 4x 3 = x 8(3)+11= 12(3) – 1 35 = 35 35 72 TUUV =

8. 120 Part + = WHOLE JK + KL = JL (4x+6) + (7x+15) = 120 11x +21 = 120 x = 9 JK=4(9)+6 KL=7(9)+15 JK=42 KL=78

9. Q PQ = QR 6x – 7 = 5x + 1 x = 8 6(8) – 7 = 5(8) + 1 41 = 41 41 PR = 82

10. N A B 59 3x+4 2x AN + NB = AB (3x+4) + (2x) = 59 5x= 55 x= 11 AN = 37 NB = 22

11.  Write your name in the top left of your notecard.  Pick any of the following three letters: A, B, or C.  Write that letter in the top right corner of your notecard.  You will complete the problem associated with your letter. Find what x equals and what each segment equals.

12. Point A is between points C and T. CA= 2x – 2 AT= 9x CT= 20 Point O is the midpoint of DG. DO= 12x – 6 OG= 10x Point N is between points A and D. AN= 5 ND= 4x – 8 AD= 3x+4 CATCAT ANDAND D OG
