A triangle has 3 interior angles that add up to 180 degrees and 3 exterior angles that add up to 360 degrees

The Interior angles of a triangle add up to 180° The Exterior angles of a triangle (or any other polygon) add up to 360°.

That's not possible.Two interior angles of a triangle can't add up to 261Â°, because all three of the interior anglesin any triangle always add up to 180Â°.

The 3 interior angles of this equilateral triangle will add up to 180 degrees

They don't. The interior angles of a triangle add up to 180°. The complements of each of these angles adds up to 360°. So 3 times 360 minus 180 = 900. This is your answer.
