ray OB is the bisector of angle AOC and ray OC is the bisector of angle BOD. m<AOD =120 find m<AOB

  • Geometry -

    Since OB bisects AOC, AOB=BOC
    Since OC bisects BOD, BOC=COD
    So, all 3 angles are equal, and are 120/3 = 40

    yeah, I know, the terminology is loose, but you can fill in the appropriate correct language
