SUMMARY
A half-circle is definitively not a parabola. While both are conic sections, they exhibit fundamentally different properties: circles maintain constant curvature, whereas parabolas have non-constant curvature. The distinction is further clarified by their definitions; a circle is the locus of points equidistant from a single point, while a parabola is defined by its relationship to a focus and a directrix. Additionally, the eccentricity of a parabola is 1, contrasting with the eccentricity of a circle, which is 0.
