An octagon has 1080 degrees total. You can find this by using the fact that the interior angles of a regular n-gon are (n-2)*180/n degrees. Multiplying that number by n gives the total number of degrees in the n-gon.
If you cut a regular octagon into triangles, it would be 6 triangles. the measurement of all the angles in a triangle added up are 180 degress multiply 6x180=1080 the measurement of all the angles in a octagon added up are 1080 degress there are 8 angles in a octagon. divide 1080 by 8=135 135 degress in each angle in a regular octagon
360 degress which is the same as the sum of the interior angles of a quadrilateral. 360 + 8 x 180 = 1800°
Each angle in a pentagon is 120 degress
a TRIANGLE HAS 180 DEGRESS! a new born knows that! LOL
