Rational points on Circles

x2+ y2 = z2 is a primitive Pythagorean triplet of positive integers (x, y, and z) that are pairwise co-prime. In this work, rational points are calculated via projection on various circles, such as x2+ y2 = 1 and x2+ y2 = 2. We find that if we have one rational point on a rational conic, then every other rational point on the conic can be represented by a reasonable parameter
