In the figure, PB is a tangent to the circle at B. R is a point on AB such that RP is the angle bisector of <APB. <BAP=h and <APR=k.
(a) Express <BRQ and <BQR in terms of h and k.
(b) Is BQR an isos. triangle?

Best ResponseYou've already chosen the best response.1is BQR an isos. triangle? we need to prove that BQR is an isos. triangle

Best ResponseYou've already chosen the best response.1since the answer is also h+k..

Best ResponseYou've already chosen the best response.1i know now, <BAC=QBP=h (<s in alt segment.) therefore, <BQR=h+k (ext. angle of triangle) is it?

Best ResponseYou've already chosen the best response.1PB is a tangent, and <BAC=<QBR (angle in alt. segment)
