Use this Interior Angle of a Regular Polygon Calculator to quickly determine each angle of a regular polygon with the regular polygon interior angle formula and calculate interior angle of polygon.
This regular polygon interior angle formula allows you to calculate interior angle of polygon for any regular polygon.
| Number of Sides (n) | Interior Angle (°) |
|---|---|
| 3 | 60.000000 |
| 4 | 90.000000 |
| 5 | 108.000000 |
| 6 | 120.000000 |
| 8 | 135.000000 |
| 12 | 150.000000 |
To manually calculate interior angle of polygon:
1. Take the number of sides (n).
2. Subtract 2.
3. Multiply the result by 180.
4. Divide by n to get each interior angle.
This Interior Angle of a Regular Polygon Calculator provides instant results with up to six decimal places using the regular polygon interior angle formula.
It is useful for students, architects, engineers, and anyone studying interior angles of polygons.
• The sum of interior angles of a polygon is always (n-2)×180°.
• Interior angles of a regular polygon are all equal.
• Polygons with more sides approximate a circle.
• Regular polygons are widely used in tiling and architecture.
• Each interior angle increases as the number of sides increases.
