What We Have Discussed?

Figures are said to be congruent if they have shape and size.

Figures are said to be similar if they have shapes but in size.

If we flip, slide or turn the congruent/similar shapes their congruence/similarity remain the .

Some figures may have more than one line of symmetry.

Symmetry is of three types namely line symmetry, rotational symmetry and point symmetry.

With rotational symmetry, the figure is rotated around a central point so that it appears two or more times same as original. The number of times for which it appears the same is called the .

The method of drawing enlarged or reduced similar figures is called Dialation.

The patterns formed by repeating figures to fill a plane without gaps or overlaps are called tessellations.
