You have to extend the line opposite to the 2 angles
For example, if u have a triangle ABC, and if BC is the base, then
if u produce BC, the exterior angle formed will be equal to angle A + angle B
OR
if u produce CB then the exterior angle will be equal to angleA+ angle C
This is true about all the sides(not only the base side)
I just gave the base as an example
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
The pairs of exterior angles of a triangle form adjacent angles with the interior angles of the triangle. Specifically, each exterior angle is supplementary to the interior angle at its corresponding vertex, meaning they add up to 180 degrees. Additionally, the exterior angles of a triangle are equal to the sum of the two opposite interior angles, establishing a relationship among them.
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
Remote interior angles are the angles that are not adjacent to a given exterior angle but are inside the triangle. For each exterior angle of a triangle, there are two remote interior angles. The sum of these remote interior angles is equal to the measure of the exterior angle. Thus, if you have a specific exterior angle, you can identify the two corresponding remote interior angles.

The sum of the interior angles of any triangle is 180 degrees.
The exterior sum of the angles of any polygon including a triangle is always 360 degrees.
They are all 60 degrees.
