## 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?

√2

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).
