the formula for the sum of the interior angles of a polygon is:
\n" ); document.write( "S = 180 * (n-2)
\n" ); document.write( "if n = 3 (triangle), then S = 180 * (3-2) = 180
\n" ); document.write( "if n = 4 (quadrilateral), then S = 180 * (4-2) = 360
\n" ); document.write( "from the formula for S, we can derive the formula for n as follows:
\n" ); document.write( "S = 180 * (n-2)
\n" ); document.write( "divide both sides of this equation by 180 to get:
\n" ); document.write( "S / 180 = n-2
\n" ); document.write( "add 2 to both sides of this equation to get:
\n" ); document.write( "n = (S/180) + 2
\n" ); document.write( "for the triangle, we get:
\n" ); document.write( "n = (180/180) + 2 which equals 1 + 2 which equals 3.
\n" ); document.write( "for the quadrilateral, we get:
\n" ); document.write( "n = (360/180) + 2 which equals 2 + 2 which equals 4.
\n" ); document.write( "if the sum of the interior angles is 4500, then the formula becoms:
\n" ); document.write( "n = (4500/180) + 2 which becomes:
\n" ); document.write( "n = 25 + 2 which becomes:
\n" ); document.write( "n = 27
\n" ); document.write( "i'm not sure what you mean by 7 right angle.
\n" ); document.write( "if you mean 7 * a right angle, then the sum would be 7 * 90 = 630 degrees.
\n" ); document.write( "the formula becomes:
\n" ); document.write( "n = (630/180) + 2 which becomes:
\n" ); document.write( "n = 3.5 + 2 which becomes:
\n" ); document.write( "n = 5.5
\n" ); document.write( "since n has to be an integer, the sum of angles equal to 630 degrees would not be possible.
\n" ); document.write( "if n is 5, the sum is 3 * 180 = 540 degrees.
\n" ); document.write( "if n is 6, the sum is 4 * 180 = 720 degrees.
\n" ); document.write( " \n" ); document.write( "
