解題步驟

1. Understand the question

   true or false:
   the sum of the angles of a triangle will always be 180°
   true
   false

2. Brief Explanations

   The 180° angle sum rule only applies to triangles on flat (Euclidean) surfaces. On curved non-Euclidean surfaces, like the surface of a sphere, the sum of a triangle's angles can be greater than 180°, and on a hyperbolic surface, it can be less than 180°. Thus, the sum is not always 180°.

3. Final answer

   False
