Some Interesting Facts About A Circle:

• A circle is a round, two dimensional shape that looks similar to the letter ‘O’.

• In strict mathematical language, circle refers to the boundary of the shape while ‘disk’ is used to refer to the whole shape, including the inside.

• A straight line from the center of a circle to the edge is called the radius.

• A straight line that passes from one side of a circle to the other through the center is called the diameter.

• The distance around the outside of a circle is called the circumference.

• All points on the edge of a circle are the same distance to the center.

• The value of Pi (π) to 2 decimal places is 3.14, it comes in handy when working out the circumference and area of a circle.

• The circumference of a circle can be found with the following formula: Circumference = π d

• The area of a circle can be found with the following formula: Area = π r²

• An arc is part of the circumference of a circle.

• A chord is a straight line joining two points on a circle, the diameter is an example of a chord (the longest possible one).

• A segment is the region between a chord and the arc it joins.

• A tangent is a straight line that touches a single point of a circle.

• A sector is the region between an arc and two radii.

• The full arc of a circle measures 360 degrees.

• A semicircle is a shape that forms half a circle, the arc of a semicircle measures 180 degrees.

• Circles have a high level of symmetry.

• A circle has the shortest perimeter of all shapes with the same area.

• The circle shape is a favorite of humans and can be seen in many designs.

• The invention of the wheel (a circle shape) was one of the most important in human history.
