How Sum of angles in a triangle is 180 degrees Actually Works
At its core, the rule that the sum of angles in a triangle is 180 degrees stems from the properties of flat (Euclidean) space. When two sides of a triangle are extended into a straight line, the three internal angles formed total exactly two right angles—a consistent outcome dependent on the geometry of flat planes. This principle applies across coordinate systems, scales, and practical uses.
