Interior Angles of a Polygon – Formula and Solved Examples

Web17 Jan 2016 · 1 Answer mason m Jan 17, 2016 20 Explanation: For a regular polygon with n sides, the exterior angle of any side is equal to exterior angle = 360˚ n Thus, in this scenario, 18˚ = 360˚ n Solve for n, the number of sides in the polygon. n(18˚) = 360˚ n = 360˚ 18˚ = 20 The polygon has 20 sides. Answer link Web2 Jan 2024 · So, the sum of interior angles of the polygon = n × 180° – 360°. = (n – 2) × 180°. Thus, the sum of interior angles of the polygon = (n – 2) × 180°. The measure of each … cinnabar perfume with essential oils

How to calculate exterior angles of a regular polygon

WebIf it is a Regular Polygon (all sides are equal, all angles are equal) Shape Sides Sum of Interior Angles Shape Each Angle; Triangle: 3: 180° 60° Quadrilateral: 4: 360° 90° … WebAnd what we had to do is figure out the sum of the particular exterior angles of the hexagon. So it would've been this angle, we should call A, this angle B, C, D, and E. And the way that we did it the last time, we said, "Well, A is going to be 180 degrees "minus the interior angle that is supplementary to A." WebSo if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A heptagon has … cinnabar perfume review
