Given:
A figure of a triangle.
To find:
The exterior angles.
Solution:
If one side of a triangle is extended, then the angle between the extended side and the other side of triangle is known as exterior angle of the triangle.
In the given figure angle 1 and angle 5 are interior angles because they are inside the circle.
In the given figure angles 2,4,6 are exterior angles because they are lie between the extended side and the other side of triangle.
Angle 3 is the angle between two extended sides. So, it is neither interior not exterior angle of the triangle.
Only 2,4,6 are the exterior angles of the given triangle. Therefore, the correct options are C, D, E.
