You can put this solution on YOUR website!
Use the 3-4-5 right triangle as an example
The longest side is the hypotenuse
According to the Pythagorean theorem,
+3%5E2+%2B+4%5E2+=+5%5E2+
+9+%2B+16+=+25+
+25+=+25+
-------------
Suppose you didn't know what one of the
smaller sides was. You could say
+3%5E2+%2B+x%5E2+=+5%5E2+
+9+%2B+x%5E2+=+25+
+x%5E2+=+16+
+x+=+4+
Hope this helps
