Exterior Angles of Polygons Worksheets

How to Determine the Measures of Exterior Angles of Polygons - It is easy to determine the interior angles of a polygon if the shape is one from the initial few polygons, like a triangle or a square or a rectangle. However, when we go down that lane, the shapes become more complex, and determining the values of their internal angles becomes more and more difficult. However, once we have calculated their internal angles, it is pretty easy to determine their exterior angles. In the case of a pentagon, for instance, the sum of all internal angles is 540 degrees, and knowing the fact that all angles are congruent to each other, we just divide 540 by '5' and get the answer to the value of a single angle. After we get the value of a single interior angle, it is not that difficult to find the value of that exterior angle. All we have to do is apply an elementary concept. At any point, a circle can be drawn, and the value of the angle made by that circle would be 360 degrees. So, we just subtract 360 by the value of that internal angle to get the value of that exterior angle.
