Example 2: Write the number of sides for a given polygon. Nonagon Triangle Pentagon Decagon Solution: 9 3 5 10 Example 3: Find the measure of each exterior angle of a regular polygon of 20 sides. Solution: The polygon has 20 sides. So, n = 20. ...
Example: Find the number of diagonals in a decagon. Solution: The number of sides in a decagon is n = 10. The number of diagonals of a decagon is calculated using the formula: n(n - 3)/2 = 10(10 - 3)/2 = 10(7)/2 = 70/2 = 35 Therefore, the number of diagonals of a de...
