WebThe Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and Exterior Angle we get a straight line 180°. They are "Supplementary Angles". Polygons. A Polygon is any flat shape with straight sides. The Exterior Angles of a Polygon add up to 360° Web26 jan. 2024 · Finding interior angles of regular polygons Finding the number of sides of a polygon. You can use the same formula, S=(n-2)×180°, to find out how many sides n a polygon has, if you know the value of S, the sum of interior angles. You know the sum of interior angles is 900°, but you have no idea what the shape is.
The sum of interior angles of polygons - Polygons - BBC Bitesize
WebThere is a useful formula for finding out the total (or sum) of internal angles for any polygon, that is: (number of sides - 2) × 180° Example: For a pentagon (a five-sided shape) the calculation would be: 5 - 2 = 3 3 × 180 = 540°. The sum of internal angles for any (not complex) pentagon is 540°. Web26 jul. 2024 · To find the sum of the interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
