Here is the unit circle with an inscribed regular hexagon divided into 6 equal \"pizza slices\" (at least for American pizza pies).
\n" ); document.write( "
\n" ); document.write( "Each \"slice\" is an equilateral triangle, with 3 congruent angles,
\n" ); document.write( "each measuring \"pi%2F3\" (since they add to half a turn =\"pi\" radians),
\n" ); document.write( "and 3 congruent sides, each with length \"1\" .
\n" ); document.write( "Two of those equilateral triangle are split into 2 congruent right triangles,
\n" ); document.write( "so the height of those triangles is \"1%2F2\" ,
\n" ); document.write( "and the angles marked with small arcs have \"sin%28theta%29=1%2F2\" .
\n" ); document.write( "Those angles measure \"theta=%281%2F2%29%28pi%2F3%29=highlight%28pi%2F6%29\" ,
\n" ); document.write( "but since angles are measured counterclockwise from the positive x-axis,
\n" ); document.write( "the angle marked with the red arc is \"pi-pi%2F6=highlight%28pi%2F6%29\" .
\n" ); document.write( "
\n" );
