Point to Tangents on a Circle
How to construct a Tangent from a Point to a Circle
using just a compass and a straightedge
- Draw a line connecting the point to the center of the circle
- Construct the perpendicular bisector of that line
- Place the compass on the midpoint, adjust its length to reach the end point, and draw an arc across the circle
- Where the arc crosses the circle will be the tangent points.
