Common Tangents
You have studied the properties and theorems of circles related to radii, chords,
secants, and tangents. These components help to create angles and segments inside
and outside a circle. However, there are also properties and components associated
with two circles together. All circles are similar to each other and all circles are
congruent when their radii have the same length. For this project, let's consider the
intersection of two circles. There are three possible arrangements.
1. No points of intersection:
АВ ВА
2. One point of intersection:
BAC. ACB
3. Two points of intersection:
D A. C. B
