What is External tangent circle

Let us study what is Externally tangent circle, Two intersecting circles in a single point is known as tangent circles. It can be divided into two types : 1. Internal 2. External By using the tangent circles many problems and constructions in geometry are solved. This types of problems have real-life applications. The followings are some real-time applications: trilateration and maximizing the use of materials. Let us see about the externally tangent circles.
