In geometry, a secant is a line that intersects a curve at a minimum of two distinct points. [1] The word secant comes from the Latin word secare, meaning to cut. [2] In the case of a circle, a secant intersects the circle at exactly two points.

Secant is the line that intersects a circle at two distinct points. Learn more about its properties, difference between tangent and secant, chord and secant and a few theorems on secant line at Cuemath

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. There are three theorems of interest here: Intersecting Secants Theorem; Intersecting Chords Theorem; Angle of Intersecting Secants Theorem

The three theorems for the intercepted arcs to the angle of two tangents, two secants or 1 tangent and 1 secant are summarized by the pictures below. If you look at each theorem, you really only need to remember ONE formula.

These "segments" may be chords, other portions of secants, and/or portions of tangents. The formulas for the lengths of these segments will be investigated.

2024年4月25日 · As discussed above, a straight line or line segment that intersects a circle at two points is a secant. A chord, on the other hand, is a line segment that joins two distinct points of the circle. In the circle shown above, AB is the chord, which is a part of the secant PQ.

In geometry, a secant is a line that cuts any curve in at least two different points. Secant means ‘to cut’ extracted from a Latin word ‘secare’. While in a circle, a secant will touch the circle in exactly two points and a chord is the line segment defined by these two points, that is the interval on a secant whose endpoints are these ...

A secant is a line that intersects a curve at a minimum of two different points. The secant line above cuts (intersects) the curve at three distinct points. In Geometry, secant lines are often used in the context of circles. The secant line below, in red, intersects the circle with center O, twice.

In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used.

Illustrated definition of Secant (line): A line that intersects two or more points on a curve. (From the Latin isecarei to cut) (Note: a line...
