WebThe proof shown in the video only works for the internal angles of triangles. With any other shape, you can get much higher values. Take a square for example. Squares have 4 angles of 90 degrees. That's 360 degrees - definitely more than 180. A regular pentagon (5-sided polygon) has 5 angles of 108 degrees each, for a grand total of 540 degrees. WebSince the sum of exterior angles of any polygon is always equal to 360°, we can divide by the number of sides of the regular polygon to get the measure of the individual angles. For example, for a pentagon, we have …

WebThe sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides. WebAn exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees. ⇒ c + d = 180° ⇒ a + f = 180° ⇒ b + e = 180° All exterior angles of a triangle add up to 360°. Proof: ⇒ d + e + f = b + a + a + c + b + c ⇒ d +e + f = 2a + 2b + 2c = 2 (a + b + c)
