Angles in any polygon
Split an n-sided polygon into (n − 2) triangles — each holds 180°. That's the whole interior-angle rule.
540°
interior sum = (5−2)×180
108° each (if regular) · 72° exterior
💡 Exterior angles always add to 360°, no matter how many sides — you make exactly one full turn walking around.
