This presentation discusses different types of symmetry. It defines symmetry as identical parts facing each other or around an axis. There are two main types of symmetry discussed - line symmetry, where a figure does not change upon reflection, and rotational symmetry, where an object looks the same after rotation. Examples are given of different geometric shapes and their number of lines of symmetry, ranging from 1 line to many lines to no lines of symmetry. Mirror images are also introduced as reflected duplications that appear identical but reversed.
