  1. No More Daily Warm Ups

  2. EOCT Week 15 #1 An equation of line a is y = x – 2.

  3. Quiz • If you didn’t do well, the test will replace your quiz grade. This just shows you some mistakes that you made. Do not be to upset about it.

  4. How do you know when two chords are congruent? • corresponding arcs are congruent B A M P b. equidistant from the center L C LP  PM ALP =  BMP = 90 D

  5. Flow Chart Proof

  6. 2x x + 40 2x = x + 40 x = 40

  7. 1. In K, K is the midpoint of RE. If TY = -3x + 56 and US = 4x, find the length of TY. U T x = 8 TY = 32 K E R S Y

  8. IF AC is the perpendicular bisector of segment DB, then… D It’s the DIAMETER!!! Arcs DC and BC are congruent!!! A C B

  9. 2. In Q, KL  LZ. If CK = 2x + 3 and CZ = 4x, find x. Q x = 1.5 C Z K L

  10. 3. In P, if PM  AT, PT = 10, and PM = 8, find AT. P A M MT = 6 T AT = 12

  11. Your turn!  4. ÐUTV ÐXTW. Find WX. y=7 WX=11

  12. Your turn!  5. Find 130º

  13. Your turn!  30 6.CE =

  14. Your turn!  7. LN = 96

  15. Segment Lengths in Circles

  16. Two chords intersect INSIDE the circle Type 1: part part part part

  17. 8. Solve for x. 9 6 x x = 3 2

  18. 12 2x 8 3x 9. Find the length of DB. x = 4 DB = 20 A D C B

  19. 10. Find the length of each chord. D x = 8 AC = 13 DB = 14 A x – 4 x C 5 10 B

  20. Two secants intersect OUTSIDE the circle Type 2:

  21. 11. Solve for x. B 13 A 7 E 4 C x D 7 (7 + 13) = 4 (4 + x) x = 31 140 = 16 + 4x 124 = 4x

  22. 12. Solve for x. B x A 5 D 8 6 C E 6 (6 + 8) = 5 (5 + x) 84 = 25 + 5x x = 11.8 59 = 5x

  23. Type 2 (with a twist): Secant and Tangent

  24. 13. Solve for x. x 12 24 (12 + x) 242 = 12 x = 36 576 = 144 + 12x

  25. 14. 5 15 x (5 + 15) x2 = 5 x2 = 100 x = 10
