To draw a tangent to a circle perpendicular to a given line, one drops a perpendicular from the centre to a parallel of the given line passing through… simply: draw the diameter parallel to the given line and the tangent at its endpoint. The tangent will be—
To draw a tangent to a circle perpendicular to a given line, one drops a perpendicular from the centre to a parallel of the given line passing through… simply: draw the diameter parallel to the given line and the tangent at its endpoint. The tangent will be—
- aperpendicular to the given line
- bparallel to the given line
- ccoincident with the given line
- dtangent to two circles

The tangent at the end of a diameter is perpendicular to that diameter. Because the diameter was drawn parallel to the given line, the tangent is perpendicular to the given line as well.
