What are some interesting facts about circles?

No matter what size the circle is, the ratio between their circumference and their diameter is always the same!

Every point on a circle is equal distance from its center

The circle is the shape with the largest area for a given length of perimeter (wikipedia)

A full circle equals 360 degrees. It includes 4 right angles that equal 90 degrees each. Half a circle equals 180 degrees. Tangent circles touch at only one point. A pair of concentric circles is one circle inside another like a bulls eye. Non concentric Circles are next to each other and do not touch. The diameter runs through the middle. The radius runs from the center to any other point on the circle. Angles are created when you draw radii.:)

circles never end. They dont have a beginning or an end, they just go round and rounnnnnddddd....

When something is in a circular shape, you can divide it equally no matter how big or small the circle is.

And finally..Circles are Fun!

infinite numbers of corners every point on perimeter is the same distance from the center a line running through a circle is a chord the circumfernece is equal to the diameter times pi the area is equal to the radius squared times pi

a circular tube as more strength then any other shape, a circle has the largest area within it compared to a shape with the same circumfrance, or measurement of the outside.

People who prefer the circle to any other shape are usually obsessed with sex.

there is an infinite amount of points on a circle.

circles are the easiest and usually first step to drawing the human figure.

circumference of a circle, area of a circle you know...

pi is infinite.

There are contests to see who can memorize it the furthest.

they're round, lol
