Answer: Choice C) Construct a tangent from an external point
=================================
Step-by-step explanation:
The idea is that you have some circle and a point outside the circle. This point is labeled M. The center of the circle is point O. A perpendicular bisector is constructed to segment OM, after which a compass is used to draw the arc marking to form point G. Line MG is perpendicular to the radius segment OG. Therefore, line MG is tangent to the circle and it goes through point M.
