WebA secant is the name given to a line which extends through a circle cutting the circumference at two points. It occurs when two chords intersect outside of the circle. For two chords, AB and CD that extend and meet at point P outside of the circle. AP : PD ≡ CP : PB where AP = AB + BP and CP = CD + DP. Therefore (AB + BP) : PD ≡ (CD + DP) : PB.

WebSep 4, 2024 · A tangent to a circle is a line which intersects the circle in exactly one point. In Figure 1 line A B ↔ is a tangent, intersecting circle O just at point P. Figure 1. A B ↔ is tangent to circle O at point P. A tangent has the following important property: Theorem 7.3. 1 A tangent is perpendicular to the radius drawn to the point of intersection.
WebA tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".) A secant line intersects two or more points on a curve. (From the Latin secare "cut or sever") They are lines, so extend in both directions infinitely. Circle On a circle they look like this: Theorems cheetah print tableclothWebA tangent is a line that touches only one point on the circumference of a circle. This point is known as the point of tangency. A tangent is always perpendicular to the radius of the circle. A chord is a line joining any two points on the circle.
