Question 1 - Think & Reflect (Page 95) How many circles pass through two points on a plane? Now, we know that Center of circles passing through two points A & B will lie on perpendicular bisector of AB Since there can be infinite points on perpendicular bisector AB, It means there can be infinite centers Thus, there are infinite circles which pass through two points A & B
