In the division algorithm, if the remainder is zero, then the algorithm terminates, resulting in a terminating decimal. remainder repeats, the calculations that follow will also repeat in a cyclical pattern causing a repeating decimal.
You can apply the Pythagorean theorem: a^2 + b^2 = c^2 c is the longest side of the triangle 2.2^2 + 4.2^2 = 6.7^2 4.84 + 17.64 = 44.89 22.48 =/= 44.89 That is not a right triangle
