If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle

60 degrees apiece.
If you mean the golden rectangle then each of its 4 interior angles measures 90 degrees but if you mean an equilateral triangle then each of its 3 interior angles measures 60 degrees
The sum of the interior angles of a triangle on a plane is always 180 degrees.
It is an equilateral triangle that has 3 equal interior angles of 60 degrees
The 3 interior angles of an equilateral triangle each measures 60 degrees
3 interior angles and each of them measures 60 degrees
All interior angles of a triangle MUST (a triangle by definition states that all interior angles MUST) add up to 180. Any measures would work, provided the three angles would add up to 180*....so a triangle with angles 1, 1, and 178 degrees works, as well as a triangle with 60, 60, and 60 degrees. Any angle combinations work, as long as the three angles add up to 180.

The 3 interior angles of this equilateral triangle will add up to 180 degrees
An equilateral triangle has 3 interior angles each measuring 60 degrees
The measures of the three exterior angles would be 95, 160 and 105.
