An exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles. This relationship is a direct consequence of the Triangle Sum Theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Consequently, the exterior angle provides valuable information about the interior angles of the triangle. Additionally, each exterior angle is formed by extending one side of the triangle, thus creating a linear pair with the adjacent interior angle.
The exterior angles of a triangle add up to 360 degrees.

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
true
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.

The exterior angles of a triangle add up to 360 degrees.

That it must be a right angle triangle because the 3rd angle must be 90 degrees
