The word quadrilateral is derived from the two latin words: ‘quadri’ means four and ‘latus’ means sides. a quadrilateral is a two dimensional shape having four sides, four angles, and four corners or vertices. the sum of internal angles of a quadrilateral is \(360^\circ \). angle sum property of a quadrilateral. For example, if we take a quadrilateral and apply the formula using n = 4, we get: s = (n − 2) × 180°, s = (4 − 2) × 180° = 2 × 180° = 360°. therefore, according to the angle sum property of a quadrilateral, the sum of its interior angles is always 360°. similarly, the same formula can be applied to other polygons. the angle sum.
