in a regular pentagon, the sides and angles are equal
\n" ); document.write( "since there are 5 angles and the whole pentagon has 3 triangles and one triangle is 180 degrees, there are 540 degrees in a pentagon
\n" ); document.write( "if X is the # of degrees in one angle of a regular pentagon, you have this equation
\n" ); document.write( "5X=540
\n" ); document.write( "so each angle is 72 degrees
\n" ); document.write( "
