Formula of Secant of a Circle
The formula for the length of a secant line (s) in a circle with radius (r) and the central angle (θ) is given by:
s = 2 × r × sin (θ/2)
where,
- s represents Length of Secant Line
- r is Radius of Circle
- θ is Measure of Central Angle formed by Secant in Radians
This formula helps in calculating the length of a secant line in a circle based on the radius of the circle and the measure of the central angle it subtends.
Secant of a Circle
Secant of a circle is a fundamental concept in geometry that can be described as a straight line intersecting the circle at two distinct points. In this article, we will understand the definition, properties, theorems, and real-world examples surrounding the concept of secants.
In this article, we will learn about the meaning of secant, the formula to calculate the secant of a circle, properties, Intersecting secants, tangent of a circle, theorem of the secant of a circle, the difference between secant, tangent, and chord, and real-life examples of Secant of a Circle.
