The ** Tangent Segment** tool lets you create a segment that is tangent to a circle, either real or imaginary. We
say

*“real or imaginary”*because really what you’re doing is selecting a center and a radius and then drawing a tangent line to that imaginary circle. If there happens to be a

**circle there too, then you’ll draw a tangent line to it. Your initial touch define the start of the tangent line. You then use the mark button**
