WebSum of the interior angles of a polygon with n sides = (n – 2) × 180° For example: Consider the following polygon with 6 sides Here, ∠ a + ∠ b + ∠ c + ∠ d + ∠ e + ∠ f = (6 – 2) × 180° = 720° (n = 6 as given polygon has 6 sides) 2. Sum of the exterior angles of polygons Sum of the exterior angles of polygons = 360° 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 …

Web25 Dec 2015 · The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides. sum of angles = (n - 2) #xx# 180 sum of angles = (7 - 2) #xx# 180 sum of angles = 5 #xx# 180. sum of angles = 900 degrees WebPentagon: The sum of the interior angles is 540°. Hexagon: The sum of the interior angles is 720°. As you can see, for each additional side of the polygon, the sum of the interior angles increases by 180°. Using this rule, we can calculate the angles of a polygon. Reason Why Sum of Interior Angles Increases by 180° for Each Additional Side riverside county mcc
