The General Rule. Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total: So the general rule is: Sum of Interior Angles = (n −2) × 180 °. Each Angle (of a Regular Polygon) = (n −2) × 180 ° / n. Perhaps an example will help: Example: What about a Regular Decagon (10 sides) ?

Interior Angle Formulas. The interior angles of a polygon always lie inside the polygon. The formula can be obtained in three ways. Let us discuss the three different formulas in detail. Method 1: If “n” is the number of sides of a polygon, then the formula is given below: Interior angles of a Regular Polygon = [180°(n) – 360°] / n ...
Interior Angles Of A Polygon. Here we will learn about interior angles in polygons including how to calculate the sum of interior angles for a polygon, single interior angles and use this knowledge to solve problems.
Interior angles refer to interior angles of a polygon or angles formed by a transversal cutting two parallel lines. Learn the different meanings with examples.
The sum of the interior angles of a polygon of 'n' sides can be calculated using the formula 180(n-2)°. Each interior angle of a regular polygon of 'n' sides can be calculated using the formula ((180(n-2))/n)°.
The sum of the interior angles of a polygon is given by the formula: sum. = 180. ( n. −. 2. ) degrees. where. n is the number of sides. So for example: In Regular Polygons. For a regular polygon, the total described above is spread evenly among all the interior angles, since they all have the same values.
The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is...
