Where is the secant of a circle?

A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.

What is secant math?

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

What is the meaning of secant in geometry?

Definition of secant 1 : a straight line cutting a curve at two or more points. 2 : a straight line drawn from the center of a circle through one end of a circular arc to a tangent drawn from the other end of the arc.

How do you solve a secant in a circle?

Two Secants Intersecting Formula: If two secant segments are drawn from a point outisde a circle, the product of the lengths (C + D) of one secant segment and its exteranal segment (D) equals the product of the lengths (A + B) of the other secant segment and its external segment (B).

How many secant can a circle have?

infinite secants
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 two points. So from the above definition, there can be infinite secants which can be drawn to the circle.

What is secant of a circle class 10?

A secant is a line that intersects the circle at 2 distinct parts.

What is the value of SEC?

The secant of angle zero degrees is written as ⁡ in Sexagesimal system and the exact value of secant of angle zero degrees is equal to one.

What is a sec math?

In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec(θ) = hypotenuse / adjacent.

What is the sec of 45?

Sec 45 degrees is the value of secant trigonometric function for an angle equal to 45 degrees. The value of sec 45° is √2 or 1.4142 (approx).
