Question

In a figure, the circle with center at C(3,-1) appears to beinscribed in triangle PQR with vertices P(-1,2)Q(3,-12), andR(7,2). a. If the equations of the angle bisectors of triangle PQR are6x+8y=10, x=3, and 3x-4y=13, is C the incenter of trianglePQR?Justify. b. From your knowledge on angle bisectors, why is the incenterequidistant from the sides of triangle PQR? c. If S(3,2) is a point on the circle, is the circle inscribedin triangle PQR?Justify. d. Write the equation of the circle. In a figure, the circle with center at C(3,-1) appears to beinscribed in triangle PQR with vertices P(-1,2)Q(3,-12), andR(7,2). a.
