Question 5 • CA-Common Core Geometry DVHS Sem. 1
Point symmetry means a figure matches itself after a 180° rotation, so any figure with point symmetry has rotational symmetry (A). Every parallelogram has point symmetry about the intersection of its diagonals, which makes D true. A triangle cannot match itself after a 180° rotation, so E is true. Rotational symmetry alone does not guarantee point symmetry: for example, an equilateral triangle matches after a 120° rotation but not after a 180° rotation. Thus B is false, and point symmetry does not require four-fold reflectional symmetry, so C is false.
