How many sides a regular polygon have
WebA regular polygon of 7 sides called a regular heptagon. The sum of all interior angles of this polygon is equal to 900 degrees, whereas the measure of each interior angle is approximately equal to 128.57 degrees. However, the below figure shows the difference between a regular and irregular polygon of 7 sides. Web8 apr. 2024 · The polygon has 19 sides. 2. Find the value of ‘x’ in the figure shown below using the sum of interior angles of a polygon formula. Solution: The figure shown above has three sides and hence it is a triangle. Sum of interior angles of a three-sided polygon can be calculated using the formula as: Sum of interior angles = (p - 2) 1800
