## Rotational Symmetry :)

Rotational symmetry is a great way to represent symmetry, it is simply how much a shape looks the same if it spins for 360 degrees. Everything has order 1 because everything always looks the same when it is where it begun if it looks the same in any other place then it is not order 1 it is obviously more. but if we look at a slide for example you would probably say its order 2 however actually its order 2 for this particular slide because of the scratches and for a square it would be 4 but if you add a dot in any inside angle it changes the order of it completely and its very weird since the circle has infinite lines of symmmetry

## Line Symmetry

Line symmetry is when you can fold something over and its exactly the same length so a square has 4 lines of symmetry however a rectangle has only 2 lines of symmetry but what is really significant is that a circle has infinite lines of symmetry exactly like rotational symmetry!

People may ask if rectangles have diagonal lines of symmetry however actually they only have vertical and horizontal
