Sum Of Exterior Angle And Interior Angles Of A Polygon. Triangles There are 3 sides and a sum of 180 degrees. In the figure angles 1 2 3 4 and 5 are the exterior angles of the polygon.
1805-25108 Therefore exterior angle is equal to 180-10872 The sum. Sum of interior angles of a polygon Angles and intersecting lines Geometry Khan Academy - YouTube. The sum of the measures of the interior angles of a polygon is always 180n-2 degrees where n represents the number of sides of the polygon.
1805-25108 Therefore exterior angle is equal to 180-10872 The sum.
The sum of interior angles differs by the number of sides polygons have. The measure of an exterior angle of a regular polygon is 2x and the measure of aninterior angle is 4x. Let n n equal the number of sides of whatever regular polygon you are studying. Click the checkboxes next to the drawing to make the interior or exterior angles.
