page 04 MARKS 5. PQR is a triangle with P(3,4) and Q(9,−2). R P (3,4) Q (9,−2) L1 (a) Find the equation of L1 , the perpendicular bisector of PQ. The equation of L2 , the perpendicular bisector of PR is y x + = 3 25. R C P (3,4) Q (9,−2) L1 L2 (b) Calculate the coordinates of C, the point of intersection of L1 and L2. C is the centre of the circle which passes through the vertices of triangle PQR. R C P (3,4) Q (9,−2) L1 L2 (c) Determine the equation of this circle. 3 2 2
