  4. In a triangle, the interior opposite angle is always less than the corresponding exterior angle. This is because the exterior angle is equal to the sum of the two remote interior angles, and hence it is greater than either of them. This question related to Chapter 6 Mathematics Class 9th NCERT. FromRead more
