1
Q
Common internal tangent
A
A tangent two both circles between the circles
2
Q
Common external tangent
A
A tangent on the outside of both circles
3
Q
How to solve internal tangent problem
A
Extend a line from one radius to the internal tangent. Then extend a line from the center of the other circle and make it perpendicular to the other line. Then solve triangle with internal tangent to get answer
4
Q
How to solve external tangent?
A
Make radio to both sides of circle. Then connect the diameters of the circles. Then cut the trapezoid j to a racy angle and triangle and solve
5
