How do you construct an exterior angle of a triangle where the sum of 2 of the interior angles is equal to an exterior angle?
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
