Interior and Exterior of Circle
If we draw a circle it divides the 2-D plane into three parts which are:
Position | Description |
---|---|
Inside the Circle | A point whose distance from the circle’s center is less than the radius; known as the interior point. |
On the Circle | Points whose distance from the circle’s center is equal to the radius; these lie on the circumference. |
Outside the Circle | Points whose distance from the circle’s center is greater than the radius; known as exterior points. |
Circles in Maths
Circles in Maths: A circle is a two-dimensional shape where all points on the circumference are the same distance from the centre. In other words, it is a collection of all points in a plane that are the same distance away from a fixed point, called the centre. Its area is equal to pi times the square of its radius.
