Three points that form the vertices of a triangle are: (-4,3), (-7, -1), (3, -2)
\n" ); document.write( "Use the distance formula to determine if the triangle is a right triangle.
\n" ); document.write( "-----------------
\n" ); document.write( "The distance is:
\n" ); document.write( " $\"s+=+sqrt%28diffy%5E2+%2B+diffx%5E2%29\"$ diffy = difference of y's
\n" ); document.write( "Subtract, then square.
\n" ); document.write( "For (-4,3) and (-7,-1):
\n" ); document.write( " $\"s+=+sqrt%284%5E2+%2B+3%5E2%29+=+5\"$
\n" ); document.write( "------------
\n" ); document.write( "Can you finish it?
\n" ); document.write( " \n" ); document.write( "
