To draw a tangent to a circle parallel to a given line, one drops a perpendicular from the centre to the line and extends it to meet the circle; at that point the tangent is—
- aperpendicular to the radius (and hence parallel to the given line)
- bperpendicular to the given line
- cthe radius itself
- da chord

A tangent is always perpendicular to the radius at the point of contact. Since that radius was drawn perpendicular to the given line, the tangent—being perpendicular to the same radius—comes out parallel to the given line.
