a=3, b=4, c=?
\n" ); document.write( "------------
\n" ); document.write( "Assuming a and b are the short sides of a right triangle:
\n" ); document.write( " $\"c%5E2+=+a%5E2+%2B+b%5E2\"$
\n" ); document.write( " $\"c%5E2+=+9+%2B+16\"$
\n" ); document.write( " $\"c%5E2+=+25\"$
\n" ); document.write( "c = 5
\n" ); document.write( "This is the 3, 4, 5 right triangle that we see a lot of.
\n" ); document.write( "Carpenters use this to see if 2 walls are at a right angle: they measure 3' from the corner on one wall, 4' on the other, and check to see if the diagonal is 5 feet. \n" ); document.write( "
