There is the Exterior Angle Inequality Theorem: If an angle is an exterior angle of a triangle, then its measure is greater than the measure of either of its corresponding remote interior angles.i don't know if that relly helps, but that's all i got

Each of the interior angles of an equilateral triangle is 120 degrees.
No. The sum of the other two interior angles.
They are all 60 degrees.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
60 degrees
60
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
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
60 degrees and it is an equilateral triangle.
