\n" ); document.write( "What kind of proof do you need?

\n" ); document.write( "M, Q, and N are collinear, with Q between M and N.

\n" ); document.write( "Triangle QPM is isosceles (PM=PQ).

\n" ); document.write( "That makes PN greater than PQ.

\n" ); document.write( "If you need a formal proof, it looks as if you can use trigonometry and the law of sines.

\n" ); document.write( "If you need a formal two-column proof using Euclidean geometry, I'm not sure how you would do it....
