**Thursday October 4th**Please take out your notes from yesterday & your workbook…**EOCT Practice**Solve the inequality d**Math II**UNIT QUESTION: What special properties are found with the parts of a circle? Standard: MM2G1, MM2G2 Today’s Question: How are chords used to find arc measures? Standard: MM2G3.a,d**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**1.**2x x + 40 2x = x + 40 x = 40**In K, K is the midpoint of RE. If TY = -3x + 56 and**US = 4x, find the length of TY. U 2. T x = 8 TY = 32 K E R S Y**IF AC is the perpendicular bisector of segment DB, then…**D It’s the DIAMETER!!! Arcs DC and BC are congruent!!! A C B**3.**IN Q, KL LZ. IF CK = 2x + 3 and CZ = 4x, find x. Q x = 1.5 C Z K L**In P, if PM AT, PT = 10, and PM = 8, find AT.**4. MT = 6 P A AT = 12 M T**Workbook**Pages 211-213 #1-24**Two chords intersect**INSIDE the circle a ab = cd d c b**Solve for x.**5. 9 6 x x = 3 2**12**2x 8 3x 6. Find the length of DB. x = 4 DB = 20 A D C B**7.**Find the length of each chord.
