SAT math question geometry about Symmetry

(E) E

Thanks!!


If a figure is rotated about a point by 180 and yet looks identical to its original, that point is called the Point of Symmetry.
Line of Symmetry is the line that divides a figure into two halves that are mirror images of each other.


Letter X is the one that has both point symmetry and line symmetry.
Letters A,B and E have only line symmetry and Z has point symmetry only.

Hope these help!!
