Geometry - Symmetry

| No Comments | 1 TrackBack

We humans are naturally attracted to symmetry. Many folks are drawn to the harmony and balance that is associated with symmetry. There is even evidence that facial symmetry impacts how attractive one person is to another. But did you know there are different types of symmetry? You've got the basic line symmetry where if you place a line over a figure dividing it in half, one side is a mirror of the other. In addition, there is rotational symmetry, where an object can be rotated and still look the same.  And finally, when dealing with three-dimensional shapes, there is plane symmetry where a plane divides the figure into two congruent, reflected halves. Learn all this and more with today's free Geometry video with Professor Edward Burger on Symmetry.
