In \(\triangle A B C\), the circle that touches the sides \(B C\) internally and other two sides \(A B\) and \(A C\) externally, is called

• Correct answer
  A

  Ex circle opposite to angle \(A\)
• B

  Inscribed circle opposite to angle \(A\)
• C

  Circumcircle of the triangle
• D

  No such circle exists

Solution

In \(\triangle A B C\), the circle that touches the side \(B C\) internally and other two sides \(A B\) and \(A C\) externally is called Ex-circle opposite to angle \(A\).
Hence, option (a) is correct.

Hence, the correct answer is option: 'A'.
