Chapter 1.4, Problem 47E

Sketch two circles that have: a No common tangents b Exactly two common tangents c Exactly three common tangents d Exactly three common tangents e Exactly four common tangents

Show construction lines and arcs for each of these exercises. Trace each circle and point in Exercises a through c and construct tangents to the circles from the given points.

Trace this line segment two times. On one copy construct a perpendicular bisector of the segment. On the other copy divide the segment into three equal segments.
