Geometry Basics:Geometry Basics consists of some basic concepts like points, lines, planes etc.Let us now understand the circle properties.We have two properties of circle. They are area and circumference of a circle.Area of a circle is how much space available inside a circle. It is measured by square units. Area of circle can be calculated by following formula,Area A = π x Radius2.Circumference of a circle is the total distance around a circle. It is measured by units. Circumference of circle can be calculated by following formula,

Circumference C = 2 x π x Radius Here π = 3.14

Let us see some sample problems of circle using symbol r.Let us lastly understand about Tangent Circles. Two intersect circles in a single point is known as tangent circles.Hope you like the above example of Goemetry Basics.Please leave your comments, if you have any doubts.
