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