Get Find The Sum Of Interior Angles Of A Nonagon Background. Another example the interior angles of a pentagon add up to 540°. The formula to find the value of an exterior angle is 360/n where n is the amount of sides.
MEDIAN Don Steward mathematics teaching: nonagon ... from 1.bp.blogspot.com Two interior angles of a pentagon measure 80° and 100°. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. A polygon is a plane shape bounded by a finite chain of straight lines.
All sides are the same length (congruent) and all interior angles are the same size (congruent).
So far i have determined that regular nongon can be inscribed into a circle. Scroll down the page for more examples and solutions on how to find missing. A polygon is a closed geometric figure which has only two dimensions (length and width). Study interior angles in geometry with concepts, examples, videos and solutions.
