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 Method 2: If … See more An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon. Or, we can say that the angle measures at the interior part of a polygon are called the interior … See more The Sum of interior angles of a polygon is always a constant value. If the polygon is regular or irregular, the sum of its interior angles remains the same. Therefore, the sum of the interior … See more Exterior angles of a polygon are the angles at the vertices of the polygon, that lie outside the shape. The angles are formed by one side of the polygon and extension of the … See more Below is the proof for the polygon interior angle sum theorem Statement: In a polygon of ‘n’ sides, the sum of the interior angles is equal to (2n – 4) × 90°. To prove: The sum of the … See more WebOct 23, 2024 · The sum of the measures of the interior angles of a polygon of n sides is 180(n - 2) If the polygon is regular, all angles are congruent, and each angle measures [180(n - 2)]/n Set the measure of one angle equal to 140, and solve for n, the number of sides.
