Interior Angles of a Regular Septagon
To find each interior angle of a regular septagon, we need to understand the properties of regular polygons and apply the formula for calculating interior angles.

Properties of a Regular Septagon:
- A regular septagon has 7 sides of equal length.
- The sum of the interior angles of a polygon can be calculated using the formula: (n-2) * 180 degrees, where n is the number of sides.

Calculating the Interior Angle of a Regular Septagon:
- Substitute n=7 into the formula: (7-2) * 180 = 5 * 180 = 900 degrees.
- To find each interior angle of the regular septagon, divide the total sum of interior angles by the number of angles: 900 / 7 = 128.57 degrees.

Conclusion:
Each interior angle of a regular septagon measures approximately 128.57 degrees. This calculation helps us understand the internal angles of a regular septagon and its properties in geometry.
