Understanding Exterior Angles of a Polygon
To find the measure of each exterior angle of a regular polygon, we can use a simple formula. An exterior angle is formed by one side of the polygon and the extension of an adjacent side.
Formula for Exterior Angles
The formula to calculate the measure of each exterior angle of a regular polygon is:
- Each exterior angle = 360° / Number of sides
In this case, we have a regular polygon with 9 sides.
Calculation Steps
1. Identify the number of sides:
- This polygon has 9 sides.
2. Apply the formula:
- Each exterior angle = 360° / 9
3. Perform the calculation:
- 360° ÷ 9 = 40°
Conclusion
Therefore, the measure of each exterior angle of a regular polygon with 9 sides is 40°.
This means the correct answer is option 'C', which is 40°.
Understanding this concept helps in various applications, including geometry and real-world situations where shapes are involved.
