 A figure is said to be symmetrical if it can be folded along an imaginary line to form
two halves that fit exactly over each other. This imaginary line is called the line of
symmetry.
 Symmetry focuses on line symmetry (or mirror symmetry), where a shape can be
folded along a line so that both halves match exactly. The line of the fold is called
the line of symmetry.
 A reflection is like a mirror image. The figure does not change on reflection. The only
change is in the orientation.
 A pattern is a sequence or arrangement of shapes, figures, or numbers in a certain
order.
 Tessellation or tiling is a pattern of geometric shapes that fit together perfectly or fill
a 2D space without any gaps or overlaps.
