How To Find The Measure Of One Interior Angle In A Polygon. In this case 1806-2 1804 720 To find one internal angle follow this formula 180n-2 n. To find the angle of any regular polygon you find the number of sides which in this example is.
Choose one vertex or corner of the polygon and draw straight lines joining this vertex to all. One way to find the sum of the interior angles of a polygon is to divide the polygon into triangles. Interior Angle Sum of the interior angles of a polygon n.
If we know the sum of all the interior angles of a regular polygon we can obtain the interior angle by dividing the sum by the number of sides.
If we know the sum of all the interior angles of a regular polygon we can obtain the interior angle by dividing the sum by the number of sides. Its just that the angles arent all congruent so you cant divide by n to get the individual measures. Take and multiply it by degrees to yield a total number of degrees in the regular nonagon. 2 X Research source.
