What shape has angles that total 180 degrees?

The shape that has angles that total 180 degrees is a triangle. In Euclidean geometry, the sum of the interior angles of a triangle is always equal to 180 degrees, regardless of the type of triangle (scalene, isosceles, or equilateral). This fundamental property allows triangles to be a crucial building block in many geometric concepts and theorems.

Other shapes, like squares and rectangles, have a total interior angle sum of 360 degrees, as they each have four right angles. A circle does not have angles in the traditional sense because it is a continuous curve rather than a polygon, and thus it does not fit within the framework of total degrees as defined for polygonal shapes.
