always 180.
A triangle
No, it is not possible to have a triangle with an angle of 181 degrees. The sum of the interior angles of a triangle is always 180 degrees according to Euclidean geometry. Any triangle with an angle greater than 180 degrees would not be a valid geometric shape.
The sum of the three interior angles inside a triangle is always 180 degrees.
triangle
A circle.
The internal angles of an n-sided shape add to (n-2)*180 degrees. So, for an 8-sided shape, they would add to 6*180 = 1080 degrees.
The three angles inside every triangle, no matter what shape or size it is, always add up to 180 degrees.
you always add on 180 degrees
I believe this is because you have added an extra angle (consider interior and exterior angle) which is 180 degrees. But, the sum of the exterior angles must always equal 360 degrees. Therefore the whole 180 degrees must be added to the sum of the interior angles. So every side that is added the sum of the interior angles adds up to 180 degrees. Hope that answers your question.
364
It could be the shape of a triangle because its 3 interior angles add up to 180 degrees
