Web13 Jun 2024 · The formula for the sum of interior angles in a polygon is (n-2) × 180°, where n is the number of sides. A pentagon has 5 sides and so, n = 5. The formula (n-2) × 180° becomes 3 × 180° = 540°. Therefore the sum of angles in a pentagon is 540°. The formula works because it tells us how many triangles can be formed inside each shape. WebIf it is a Regular Polygon (all sides are equal, all angles are equal) Shape Sides Sum of Interior Angles Shape Each Angle; Triangle: 3: 180° 60° Quadrilateral: 4: 360° 90° Pentagon: 5: 540° 108° Hexagon: 6: 720° 120° Heptagon (or Septagon) 7: 900° 128.57...° Octagon: … Interior Angle An Interior Angle is an angle inside a shape.
