www.ck12.orgChapter 1. Angles of Chords, Secants, and Tangents Solution: Use Theorem 9-11. a) m6BAD= 1 2 mABc= 1 2 124 =62 b) mAEBd=2m6DAB=2133 =266 Example 2: Find a;b, and c. Solution: To find a, it is in line with 50 and 45 . The three angles add up to 180 . 50 +45 +m6a=180 ;m6a= 85 . b is an inscribed angle, so its measure is half of mACc.
ANGLE-CHORD-SECANT THEOREMS: m∠1 = 1 2(mAD+!mBC!) AE • EC = DE • EB A m∠P = 1 2(m!RT!m!QS) PQ · PR = PS · PT D A E B C 2 1 R T P S Q E xample1 If the radius of the circle is 5 units and AC = 13 units, find AD and AB. A B C D AD!CD and AB!CD by Tangent/Radius Theorem, so AD 2+CD =AC 2 or AD 2+5 2=13 2. So AD = 12 and AB!AD so AB = 12. E 2
