A pat on the back Nothing Applause 3 pts EC on test!! Cookies! Candy High Five Three Cheers! Good Luck! Applause A big smile Donut holes!! 3. 2. 4. 7. 10. 5. 8. 11. 6. 9. 12. 1.

1. OE bisects VOL Write all possible true equations from the diagram. 5x + 4 L O V E 7x – 14 10x + 8 I.5x + 4 = 7x – 14 II.5x + 4 + 7x – 14 = 10x + 8 III. 2(5x + 4) = 10x + 8 IV. 2(7x – 14) = 10x + 8 What if OE were NOT a bisector? Only # 2!!

R Y L I E M Y is the midpoint of RL YI bisects LYE 2. How do you know: a) Y is the midpoint of RL. a) Given. b) RY + YL = RL. b) Segment addition post. c) MYR + RYE = MYE c) Angle addition post. d) LYI IYE d) Def bisect

3. Five times an angles supplement is 30 less than the angle. Find the measure of the angles supplement. 5(180 – x) = x – 30 900 – 5x = x – 30 930 = 6x 155 = x Supplement = 180 – 155 = 25

11x - 6 8x + 34 x + 25 4. Write all possible true equations from the diagram. I.x + 25 + 11x – 6 = 180 II.11x – 6 = 8x + 34 III. 8x + 34 + x + 25 = 180

U 5. O S T H W 1 2 3 a) 2 3 a) Vertical Angle Thm How do you know that: b) TO + OW = TW b) Segment Addition Postulate c) 1 + 2 = HOW c) Angle Addition Postulate d) SO + OU = SU d) Segment Addition Postulate

6. Find the perimeter of the parallelogram 3x + 20= 5x 20 = 2x 10 = x x + 8 x (5x)˚ (3x + 20)˚ = 10 + 8 = 18 = 10 P = 10 + 18 + 10 + 18 = 56

7. Twice an angle is 6 more than its supplement. Find the measure of the angles complement. 2x = 6 + 180 – x 3x = 186 x = 62 complement = 28˚

8. x + 3 P = 24 + 15 + 24 + 15 = 78 3x – 12 Find the perimeter of the parallelogram 3x – 12 = 2x x = 12 2x = 2(12) = 24 = 12 + 3 = 15

How do you know that: 9. a) RY + YL = RL a) Segment Addition Postulat e b) RY YL b) Definition of Midpoint c) RYM IYL c) Vertical angle thm d) RYI + IYL = RYL d) Angle Addition Postulate e) RYI + IYL = 180 e) Definition of Linear Pair f) EYI IYL f) Definition of bisect R Y L I E M Y is the midpoint of RL YI bisects LYE

(5x + 3)˚ (6x – 4)˚ 10. Write all possible true equations from the parallelogram. (8x – 12)˚ I.6x – 4 + 8x – 12 = 180 II.6x – 4 + 5x + 3 = 180 III. 8x – 12 = 5x + 3

10x + 8 3x + 2 11. Write all possible true equations from the parallelogram. I.8x + 16 = 10x + 8 II.Nope! Thats it 8x + 16

1 2 3 4 5 6 7 8 List all pairs of: a) Alt int a) 7 & 3; 2 & 6 b) SSE b) 8 & 5; 1 & 4 c) Alt ext c) 8 & 4; 1 & 5 How do you know that: d) 7 3 d) // lines alt int s e) 7 supp 6 e) // lines SSI s supp f) 8 6 f) // lines corr s
