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.
never
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.
In any triangle exterior angle plus interior angles = 180 degrees
It is: 180-interior angle = exterior angle
