A nice little puzzle in number cruching and trigonometry?
If I tell you that the smallest side of a right-angled triangle is 19cm, can you compute the value ( in whole numbers) for the other two sides ? I will tell you that all the sides are less than 200cm.

we know that all odd numbers are the lowest of a Pythagorean triple x,y,z. x = the difference of two squares, m^2 - n^2, and y = 2mn. In this case since 100 - 81 = 19, the sides of the triangle are 19, 180, and 181.

if you start at 200 and work your way down all you have to do is square the no. take away 19 squared (361) and then find the square root of that . keep going till you find a whole no. would give the answer but cant be bothered to sit here working it out.
