Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
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
They are all 60 degrees.
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.

That depends on what type of triangle it is but in general:- 180-interior angle = exterior angle
exterior angle theorem
any other exterior angle of the triangle * * * * * No. The sum of the two opposite interior angles.
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
No. The sum of the other two interior angles.
To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.
In any triangle exterior angle plus interior angles = 180 degrees
