To prove that the sum of angles of hexagon is 720 degree

Open in App

Solution

The sum of the interior angles of ahexagon is 720 dgrees. You can have 6 triangles in a hexagon if you join vertices to the centre. So on account six triangles 6180degrees minus the angle at the centre which is 360. or 1806-360 = 720 degrees is the sum of the interor angles of a six sided polygon or hexagon
