+How to find the tangent of a point off a circle:
+
+ •  Calculate the midpoint on the point and the center of the circle
+ •  Get the length of the line segment from the and the center divided by two
+ •  Use that length to construct a circle with the point at the center and the
+    radius equal to that length
+ •  The intersection of the two circles are the tangent points
