Any exterior angle of a triangle always equals the sum of the two interior opposite angles.

They are all 60 degrees.

An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.

measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B

Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle

The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
