Tángent n.s. [tangent, Fr. tangens, Lat.]

Tangent, in trigonometry, is a right line perpendicularly raised on the extremity of a radius, and which touches a circle so as not to cut it; but yet intersects another line without the circle called a secant that is drawn from the centre, and which cuts the arc to which it is a tangent. Trevoux.

Nothing in this hypothesis can retain the planets in their orbs, but they would immediately desert them and the neighbourhood of the sun, and vanish away in tangents to their several circles into the mundane space. Bentley's Serm.
