Question

If a(3,-4),b(7,2) are the ends of a diameter of a circle and c is a point on the circle then circumcentre of triangleabc is​

Answer 1

Answer:

(5,-1)

Step-by-step explanation:

since the circumcentre is at the midpoint of the diametrically opp. ends so

(x,y)= [(3+7)/2 ,(-4+2)/2}= (5,-1)

Answer 2

Answer:

Step-by-step explanation:

Given that points A and B are the endpoints of diameter a circle . Point C lies on the circle . Then :A(3,-4) = (a,b)B(7,2) = (d,c)C(3,2) = (a,c) Orthocentre of ∆ABC is given by :O(x,y) = (Repeated abscissa, Repeated ordinate)O(x,y) = (a,c) = (3,2) I e Point C
