Websum of interior angles = 180∘ ×(number of sides− 2) sum of interior angles = 180 ∘ × ( number of sides − 2) This means the interior angles of a triangle add up to 180° × (3 − 2), or 180°. Any four-sided polygon will have interior angles adding to 180° × (4 − 2), or 360°. A chart can be made of these:
