That depends on what type of triangle it is but in general:-
180-interior angle = exterior angle
No. The sum of the other two interior angles.
No.
Remote interior angles.
Yes, it is.
It is 3.
never
No. The sum of the other two interior angles.
exterior angle theorem
Measure of angle 1?
the exterior angle theorem
For a polygon with n sides (n angles), there are (n - 1) remote interior angles for each exterior angle.
No.
Remote interior angles and remote exterior angles.
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
Are two angle of a triangle that are not adjacent to the exterior angle
Remote interior angles
Remote interior angles.
