E intersects the incenter, so it is an A bisector. 26. neither 2?. neither 45. 1‘: 4 46. x = 4.2 Solutions: Chapter 5 Properties and Attributes of Triangles Lesson 5-2 Bisectors of Triangles; 2. 3. circumscribed about N is the circumcenter of APOFi‘. By the Circumcenter Theorem, N is equidistant from vertices of APOFi. NR = NP = 5.64 4. RV: PV= 5.47 . TH: OT: 3.95 6. N is the circumcenter of APOFi. By the 1D. 12. 13. 14. 15. 1B. 19. 22. Circumcenter Theorem, N is equidistant from vertices of APQFL 0N = NP = 5.64 . F is the incenter of ACDE. By the Incenter Theorem, F is equaldistant from t_he sides of A005. The distantfifrom F to DE is 42.1, so the distance from F to CD is also 42.1. macs: 2m4FCD mADCE: 207°) = 34° mADCE + mACDE + mLCED = 130° 34 + 54 + mACED = 180° mACED = 92° mZFED = mACED l 2 mAFED = %(92°) = 46° CF: FA = 59.? Y0 = YB = 63.9 DB = A0 = 62.8 AY = Y8 = 63.9 J is the incenter of AFi’ST. By the Incenter Theorem, J is equaldistant from the sides of ARST. The distance from J to Wis 8.37, so the distance from J to % is also 8.37. mATSFt = 2mAJSFi’ mATSFi = 2(14°) = 28° mATSFi' + mASFiT+ mAFtTS = 180” 28 + 42 + mATSR=180° m4 TSFi’ = 110° mAFi'TJ = émé Tsn mAFi’TJ =%(110°) = 55° The angle bisector; szAE = mAEAC Solutions: Chapter 5 Properties and Attributes of Triangles Lesson 5-2 Bisectors of Triangles; 23.
