That forms 2 Right Triangles with the diagonal right?
\n" ); document.write( "See below,
\n" ); document.write( "
\n" ); document.write( "In a Pyth. theorem, a Right Triangle with \"hypotenus=5m\" (diagonal), has other sides measure: \"opposite=Width=3m\" and \"adjacent=Length=4m\"
\n" ); document.write( "Proof: Pyth.Theorem:
\n" ); document.write( "\"5%5E2=3%5E2%2B4%5E2\"
\n" ); document.write( "\"25=9%2B16\"
\n" ); document.write( "\"25=25\", good
\n" ); document.write( ".
\n" ); document.write( "Therefore, \"Area=%281%2F2%29bh=%281%2F2%29L%2AW=%281%2F2%293%2A4\"
\n" ); document.write( "\"Area=6m%5E2=A%5B1%5D=A%5B2%5D\"
\n" ); document.write( "Since it forms 2 triangles:
\n" ); document.write( "\"Area%5BR%5D=A%5B1%5D%2BA%5B2%5D\"
\n" ); document.write( "*Note: \"A%5B1%5D=A%5B2%5D\"
\n" ); document.write( "
\n" ); document.write( ".
\n" ); document.write( "\"Area%5BR%5D=6m%5E2%2B6m%5E2=highlight%2812m%5E2=A%5BR%5D%29\", ANSWER
\n" ); document.write( ".
\n" ); document.write( "*Now, this is misleading data, having \"P=18m\". It doesn't make sense. If we calculate \"Perimeter=2%28L%2BW%29=2%283%2B4%29=2%287%29=14m\" , Does not match up. PLEASE VERIFY THIS.
