Pythagorean triplets are numbers such that the sum of the squares of two numbers equals the third number. Pythagorean triplets form the three sides of a right-angled triangle.

Observe that ${15}^2+8^2=225+64=289={17}^2$ and hence the numbers form a Pythagorea triplet.
Likewise, ${12}^2+{16}^2={20}^2$ and ${.03}^2+{.04}^2={.05}^2$
