Consider a triangle PQR with coordinates of its vertices as P(-8,5), Q(-15, -19), and R (1, -7). The bisector of the interior angle of P has the equation which can be written in the form ax+2y+c=0. The distance between the orthocenter and the circumcenter of triangle PQR is

In DeltaPQR , the equation of the internal angle bisector of angle Q is y = x and the equation of side PR is 3x-y=2 . If coordinates of P are (3, 2) and 2PQ = RQ , then the coordinates of Q are

Three vertices of triangle ABC are A(–1, 11), B(–9, –8) and C(15, –2). The equation of angle bisector of angle A is

If p and q are the roots of the equation x^2 - 15x + r = 0 and. p - q = 1 , then what is the value of r?
