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
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
They are all 60 degrees.
never
That depends on what type of triangle it is but in general:- 180-interior angle = exterior angle
exterior angle theorem
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
any other exterior angle of the triangle * * * * * No. The sum of the two opposite interior angles.
No. The sum of the other two interior angles.
It is: 180-interior angle = exterior angle
It is: 180-interior angle = exterior angle
