C (O, r1) and C (O, r2) are two concentric circles with r1 > r2. AB is a chord of C (O, r1) touching C (O, r2) at C then
  • a)
    AB = r1
  • b)
    AB = r2
  • c)
    AC = BC
  • d)
     AB = r1 + r2
Correct answer is option 'C'. Can you explain this answer?

Given that AB is chord of bigger circle and it is tangent to a smaller circle touching at C.
Then AB is perpendicular to OC. C is mid point of AB then AC = BC.

And r2 as their radii respectively. The center of both circles is O.

If r1 < r2,="" it="" means="" that="" the="" radius="" of="" c="" (o,="" r1)="" is="" smaller="" than="" the="" radius="" of="" c="" (o,="" r2).="" in="" other="" words,="" c="" (o,="" r1)="" is="" a="" smaller="" circle="" nested="" inside="" c="" (o,="" />

If r1 = r2, it means that the radius of C (O, r1) is equal to the radius of C (O, r2). In other words, both circles have the same size and are therefore identical.

If r1 > r2, it means that the radius of C (O, r1) is larger than the radius of C (O, r2). In other words, C (O, r1) is a larger circle that encompasses C (O, r2) within it.

In summary, the relationship between the two concentric circles depends on the relative sizes of their radii.
