the common answer is 180. However some say it could be less or greater. I request a mathemetation to answer the question.

Brilliant question. A triangle has 3 angles that may not add upto 180* or may exceed 180*. If the triangle lies on a plane, then the sum is 180*. On the other hand, if the triangle lies on a sphere, then a convex triangle exceeds 180* , concave triangle does not reach 180*.
For example, consider 2 longitudes on the surface of earth. They meet at the poles, and they form a triangle with the equator. Now, longitudes are parallel at the equator, so the sum of two interior angles = 180*. The third angle is extra. This is non-eucleadian geometry.

The sum of the interior angles of any triangle equals 180 degrees.

I didn't know that the sum of the 3 interior angles in a triangle could be more or less than 180 degrees. If you are just like me who studied math 50 years ago, the answer to your question is 180 degrees, no more no less.

By defintion it's 180, if you use the 360 degree circle. Engineers use a 400 gradian circle , so for them a triangle has 200 gradians. Grad is found on your calculator. 100 grads = 90 degrees.

The sum of all the interior angles of a triangle always equals 180.

180 degrees no doubt, no other answer. The same of interiors of a triangle add up to 180, its just one of its properties.
