1. the state or condition of being tangent; the quality of touching at a single point without intersecting
Usage: mathematics; geometry

Examples

• The tangency of the circle and the line occurs at exactly one point.
• In geometry class, we studied the tangency between two circles.
• The engineer calculated the point of tangency for the curved road design.
• The tangency condition ensures that the surfaces meet smoothly.
• At the point of tangency, the two curves share the same slope.
• The mathematician proved the tangency relationship between the parabola and the circle.
