180 degrees
The sum of the interior angles of a triangle on a plane is always 180 degrees.
two opposite interior angles.
The three interior angles of any triangle always add up to 180 degrees.
180 degrees because the 4 interior angles of a quadrilateral add up to 360 degrees and the 3 interior angles of a triangle add up to 180 degrees
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
