In a triangle, the sum of the interior angles always equals 180 degrees. This is a fundamental property of Euclidean geometry that applies to all types of triangles, regardless of their shape or size. When you take each of the three angles in a triangle and sum them together, you will always arrive at this consistent total.

This property can be understood by visualizing a triangle drawn on a flat surface. If you were to draw lines from each vertex to the opposite side, you could create different angular relationships, but the total would remain the same. Triangles can be categorized as acute, right, or obtuse, yet the total measure of the angles remains constant across these categories.

This principle is not only critical for understanding basic geometric concepts but also for solving more complex problems involving triangles in various mathematical applications.
