The interior angle of a polygon is defined as the angle formed between two adjacent sides, while the exterior angle is formed between one side of the polygon and the extension of an adjacent side. To calculate these angles, specific formulas are used.Interior Angle FormulaThe formula for calculating the interior angle of a regular polygon is given by: (n-2) × 180° / n, where n is the number of sides. For example, in a hexagon (6 sides), the interior angle would be (6-2) × 180° / 6 = 120°.Exterior Angle FormulaThe exterior angle can be calculated using the formula: 360° / n. This means that for the same hexagon, the exterior angle is 360° / 6 = 60°. Interestingly, the interior and exterior angles of a polygon are supplementary, meaning they add up to 180°.Real-World ApplicationsUnderstanding these angle formulas is crucial in fields like architecture and design. For instance, when designing a room, you might want to consider how the angles of walls will affect space utilization and aesthetics. A well-planned angle can enhance natural light and improve the overall flow of a space.FAQWhat is the sum of the interior angles in a polygon?The sum of the interior angles in a polygon is given by the formula (n-2) × 180°.welcome to CoohomHome Design for FreePlease check with customer service before testing new feature.
