Answer:

Q2. The exterior angles formed at each vertex of a triangle are never equal. But they can be equal if a triangle is an equilateral triangle.

Q3. The sum of an exterior angle of a triangle and its adjacent interior angle is 180 degree because they make a linear pair. Also the sum of the two opposite angles to the exterior angle is equal to the measure of the exterior angle.
