# 19 Awesome Sum Of Measures Of Interior Angles Of Decagon

Sum Of Measures Of Interior Angles Of Decagon coolmath reference polygons 10 decagonsThe measure of the central angles of a regular decagon To find the measure of the central angle of a regular decagon make a circle in the middle A circle is 360 degrees around Divide that by ten angles So the measure of the central angle of a regular decagon is 36 degrees Sum Of Measures Of Interior Angles Of Decagon 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

cliffsnotes Study Guides GeometryExample 1 Find the interior angle sum of a decagon A decagon has 10 sides so Example 2 Find the exterior angle sums one exterior angle at each vertex of a convex nonagon The sum of the exterior angles of any convex polygon is 360 Example 3 Find the measure of each interior angle of a regular hexagon Figure 3 Sum Of Measures Of Interior Angles Of Decagon khanacademy Geometry foundations PolygonsClick to view4 28Mar 25 2017 And so if we want the measure of the sum of all of the interior angles all of the interior angles are going to be b plus z that s two of the interior angles of this polygon plus this angle which is just going to be a plus x a plus x is that whole angle Author Sal Khan 11 2008 Best Answer Interior angle sum of a polygon 180 n 2 where n is the number of sides For a decagon n 10 thus Angle sum 180 10 2 180 8 1440 degrees You can also use the triangle method the above formula is derived from this method only Construct a decagon and consider any of its 10 Status ResolvedAnswers 5
