 Question 602769: Hello, would any tutors please help me with these problems? I don't really understand how to do them. If also you can explain how you did them, I would be really thankful. Thank you for your time!!! http://i90.photobucket.com/albums/k250/robinahood11/photo22.jpgAnswer by mananth(12270)   (Show Source): You can put this solution on YOUR website!13.A A(2,8) B(0,8) C(2,2) Let O be the center of the circle circumscribing the triangle Then d(OA)=d(OB)=d(OC) all are radii. Let the coordinates of be (x,y) The distance between two points (x1,y1) & (x2,y2) is given by d= O(x,y) & A(2,8) d(OA)= = = B(0,8)O(x,y) d(OB)= = Since OA & OB are radii They are equal = square both sides -4x=-68+64 =-4x=-4 x=1 C(2,2) O(x,y) D(OC)= = = d(OC)=d(OA) = square both sides = 12y=60 /12 y=5 The center (1,5) 17 bisector 18 median 19 altitude m.ananth@hotmail.ca
