**How To Calculate Interior Angles** Angles33 3 Views 84KLast updated Aug 15 2018Published Nov 01 2014 **How To Calculate Interior Angles** khanacademy Geometry foundations PolygonsClick to view4 28Mar 25 2017 And we also know that the sum of all of those interior angles are equal to the sum of the interior angles of the polygon as a whole And to see that clearly this interior angle is one of the angles of the polygon This is as well Author Sal Khan

sum exterior angles polygon The angles of a regular polygon are equivalent and their sides are as well The sum of the exterior angles of a regular polygon will always equal 360 degrees To find the value of a given exterior angle of a regular polygon simply divide 360 by the number of sides or angles that the polygon has **How To Calculate Interior Angles** can I calculate the interior angle of a So to calculate the internal angles of a decagon Draw a regular decagon Mark the centre and draw lines to 2 adjacent vertices Draw a line to the next vertex each side as well Notice that you have a bunch of isosceles triangles that each interior angle is made up of one angle from each pair of adjacent triangles

angles polygons htmlThe Interior Angles of a Quadrilateral add up to 360 Because there are 2 triangles in a square The interior angles in a triangle add up to 180 and for the square they add up to 360 because the square can be made from two triangles **How To Calculate Interior Angles**
