Draw & Identify Common Tangents | External & Internal | Geometry | Eat Pi
In this video, I teach you how to draw and identify common tangents between two circles. I also cover how to identify common internal and external tangents, which can be done by drawing a straight line from one circle to another. There are 3 different cases you will see: intersections at 2 points, 1 point, and no points. I do an example of each one.
0:00 - Not Intersecting - 4 Tangents
1:48 - Not Intersecting - No Tangents
3:08 - 1 Intersection - 1 Tangent
4:19 - 1 Intersection - 3 Tangents
5:23 - 2 Intersections - 2 Tangents
