what is the difference between a chord and secant
What is the difference between Chord, Tangent and Secant? â¢ A chord is a line segment and both secant and tangents are straight lines. â¢ Chord is a line segment with the end points lying on a curve while a secant is a line passing through exact two points on a curve. â¢ A tangent is a line that just touches and passes through a point on a curve. It is a special case of secant where the two points on the curve overlap.
