**Exterior Angle Equation** and exterior angles of a polygonExterior angle An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side Interior and exterior angle formulas The sum of the measures of the interior angles of a polygon with n sides is n 2 180 **Exterior Angle Equation** angle theorem definition formula htmlThe exterior angle theorem tells us that the measure of angle D is equal to the sum of angles A and B In formula form m D m A m B Think back to our common fact that a straight line is equal

angle theorem htmlExterior Angle Theorem This video discusses the exterior angle theorem It also defines what exterior and remote interior angles are It solves two example problems in detail The first example problem is pretty basic The second example problem is much harder An exterior angle is an angle formed by the extension of one side of a triangle **Exterior Angle Equation** khanacademy Geometry foundations PolygonsClick to view5 24Sal demonstrates how the the sum of the exterior angles of a convex polygon is 360 degrees 8 exterior angle theoremImprove your math knowledge with free questions in Exterior Angle Theorem and thousands of other math skills

exterior angle is the supplementary angle to the interior angle at the vertex of the polygon so in this case each exterior angle is equal to 45 degrees 180 135 45 Remember that supplementary angles add up to 180 degrees 4 9 5 **Exterior Angle Equation** 8 exterior angle theoremImprove your math knowledge with free questions in Exterior Angle Theorem and thousands of other math skills 15 2008 The sum of the exterior angles is always 360 so if the angles are all the same regular polygon each exterior angle is 360 n where n number of sides And exterior interior 180 so the interior angles each measure 180 minus that 180 360 nStatus ResolvedAnswers 5
