### Understanding the Equation $CD^2 = x^2 + y^2 + (z - 1)^2 = 2$ in Geometry and Applications The equation $CD^2 = x^2 + y^2 + (z - 1)^2 = 2$ represents a key geometric concept in three-dimensional space. While $CD^2$ widely appears in distance and squared-distance notations, in this specific form it defines a precise geometric object: a sphere in ÃƒÂ¢Ã‚Â„Ã‚ÂÃƒÂ‚Ã‚Â³. --- ### What Does $x^2 + y^2 + (z - 1)^2 = 2$ Mean?
