Question

A toy manufacturer needs a piece of plastic in the shape of a right triangle with the longer leg 2 cm more than the shorter leg and the hypotenuse 2 cm more than the longer leg. How long should the sides of the triangle be?

Answer 1

Short leg = 6, Long leg is 8, and hypotenuse is 10. Just for proof (6^2+8^2) = 100, the square root of that is 10. 

Answer 2

The only Pythagorean triple that is an arithmetic sequence is (3, 4, 5). If the side lengths differ by 2 cm, they must be ...
6 cm, 8 cm, 10 cm
