That's not possible.
Two interior angles of a triangle can't add up to 261°, because all three of the interior angles
in any triangle always add up to 180°.
the exterior angle theorem
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
never
Each exterior angle measures 10 degrees Each interior angle measures 170 degrees
Each exterior angle measures 11.5 degrees. Each interior angle measures 168.75 degrees
In any triangle exterior angle plus interior angles = 180 degrees
exterior angle theorem
two opposite interior angles.

They are all 60 degrees.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

It is an indication of an error, or the fact that the triangle is not in the Euclidean plane but on a convex surface.
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
number of sides = 360/exterior angle = 360/120 = 3 polygon is therefore a triangle, interior angles total 180o
