Q2. What is a Tangent Generally?
Answer: A tangent in common can be any line, segment or a ray that can be a tangent to more than one circle simultaneously. There can be 1 to 4 numbers of common tangents to two circles. The point to be taken a note of is that a circle's tangent touches the circle but never really enters it. Moreover, multiple tangents to the 2 circles can be an inner tangent or an outer one to each other’s circles.
